Because Robot allows several design optimization options, design currently cannot be performed for both service and ultimate at the same time.

This virtual wind tunnel will allow you to get a powerful view into the behavior of wind around your structure and potentially inform your design in areas where there are higher than expected pressures. Imagine gaining confidence in your code wind loading analysis by running a virtual wind tunnel and seeing that you have sufficiently modeled the wind loading on the building.

Full loading is automatically created on your structure according to the analysis. This is really the beginning of real simulation tools for structural engineers to help us design safer structures than we have ever been capable of before.

Block Lanczos solver: In simplest terms, the Block Lanczos solver increases the speed and efficiency of dynamic calculations in modal analysis. It is one of the most. Improved bi-directional model data exchange between Autodesk Revit Structure and Robot Structural Analysis: Autodesk had produced a much more robust method of interchange of data based on an interchange format called SMX Structural Model Exchange.

Other advantages of the SMX format include enhanced change tracking and smaller, more efficient, file transfers. Joists and Joist Girders are primarily used by North American engineers. Cut By Plane: A new editing tool which will allow the user to divide contour edges, create nodes at intersections of a plane and objects in the model, split objects by a plane as well as cut objects by a plane. Simply clicking on one will open that model.

You may also choose Open Project Shell Design: All tools except volumetric extrusions available. Frame 2D Design: Tools optimized for 2D frame work. Inversion: Invert current s ction. Le, select all elements except the currently selected elements Exercise 4: Using the Selection Dialog 1. Open the Exercise Userlnterface.

Use the display settings to show member sections and member types: On the right hand side choose W16x40 and press Hfl The selection area should say: 55 56 60 62 65to68 and you will notice that all W16x40s in the project have been selected. Build the same selection in the following manner: a. We have some mismatched member types that we need to clean up. We will use the union button to find all columns which have a beam member type set. Clear the current selection and select HSS 5x5x.

The recommended practice is to set your regional settings, then adjust design codes on a project by project basis. Due to the automatic changes it is not recommended to change your Regional setting once you have started a project. Choose your working language from the drop down list. In any edit control where you can reasonably type a number e. If launched from an edit control text box , the OK button will take the current result and paste it into the edit control.

There are several preconfigured settings available from the drop-down list. You can also create your own custom scheme. However, sometimes it is nice to add your own style to the display window. The template controls settings for all elements in all ranges. On the first pane of the Units and Formats, the zero format controls how Robot will display a value if is equal to 0.

Left and Right arrows decrease and increase displayed precision. Unit edition is a bit of a misnomer. If there is not an existing unit you would like to use, you can create your own Length, Force or Mass units using this tab. All units are based on Meters, Newtons and Kilograms.

Notice that the inch unit is 0. Hach segment of the tab works independently: Length unit, Force unit and Mass unit. Here is an example of some very unique unit settings. As you create bars of different materials, these are the materials which will be assigned by default. It is best to set the most commonly used materials for structural elements here, then modify specific ones later. Other database lists work similarly.

Not all design modules support all geo design codes. List can be sorted by clicking on the column header. This dialog allows you to manage that list complexity by only showing you the codes in the Active list when you configure design codes for your project.

Different solvers have been added over time and most are different methods of exploiting standard structure stiffness matrix properties to accelerate the solution as well as to take advantage of computer memory savings by reducing storage requirements. Selecting different solvers can have advantages or disadvantages depending on the number of equations, the stability of the matrix and other factors.

Additionally, information on solution algorithms and their methods of solution can be found in texts on the subject of finite element analysis. Specific information on advantages and disadvantages and solution methods ean also be found in the Robot help files.

In general, it is best to ask Robot to Not Ignore Warnings so that as you learn the Product you can understand and deal with any issues in your model and also understand how they may affect your results.

You can read more about them in the help files but we will leave discussion of these options to an advanced text, Other subsections of this dialog contain settings for advanced analysis options.

In this text we will focus on methods of working with Robot for the beginner. Advanced topics such as modal analysis, and analyses based on a modal analysis e. This dialog provides a location for recording information about the project, the parties involved as well as a tab for viewing information about the project Statistics tab.

Once you have completed this chapter, you will be able to run your first analysis and will be ready to learn about Robot’s results exploration capabilities. They can be used to. We will discuss grid modification later. Since our task at hand is to create the structure model geometry, we select Geometry from the layout, selector. Hither select an existing axes set to modify in the drop down or type in a name for a new set.

Cartesian grids may be orthogonal to the project axes or be at an arbitrary angle. They may also be relative to a pointin the model. Any coordinate point in Robot may be specified by clicking on the screen. Simply place the focus on that edit box by clicking once in the edit box, then select a location on screen.

Use Axes relative to a point to place the origin of the axis set at the location of the selected point. It is the origin 0,0,0 by default. An axis set may be rotated about any of the three project axes X, Y, or Z allowing for many possibilities for structural axes set configurations.

Cylindrical Parameters: 4 Select to define grids along corresponding axis. Same for Y and Z axes. Each tab is the same. If you intend to do building analysis and seismic analysis in particular, you should opt for using Stories and leave the Z axis settings blank for structure grids. Axis set labels: Lists the currently configured axes along the current axis specified by the tab, e.

Individual axes labels can be modified by clicking them, but to change the location of the axis, either use the object properties in the project environment or delete the grid and re-create it here. Numbering can be numerical or alphabetical 1,23 or A,B,C which is automatically incremented as you add new grids to the dialog. You can also have the label be the geometric position of the grid i. Axis Manager is where you manage axis sets and their visibility in the project.

You can have any number of axis sets that you require to help layout your project. Unchecking them in this dialog will turn off their visibility in the project. Previously created sets may be viewed or modified with the dropdown selector Item 1 above. Exercise 5: Creating Structure Axes: 1. Start a new project in Robot and select Shell structures: a. Ifyou started the Shell type structure, the default orientation for the project view is the ZX plane so all of our created grids will not be visible yet.

We could type in coordinates here, but this time we will pick a coordinate from the project environment. The checkbox controls visibility in the project. Stories can also be used to select elements which either lie on the story or are part of the — story.

While you may use this graphical definition feature in any view orientation, this is most easily accomplished in a view oriented to the XZ or YZ planes. If the last character in the template is a letter then levels will be alphabetical, if it is a number then they will be numerical. All other characters before the last one will simply prepend the incremented value the last character. All characters to the left of Yv will make up the first part of the name.

Assigning Elements to Stories Once you have your stories defined, elements floors, walls, beams, columns, braces, ete will need to be assigned to their respective stories in order for any seismic analysis to be performed. If you model your structure one story at a time, setting your workplane as you go, you will find that elements are automatically assigned to stories as you create them. Robot offers a quick tool to help out in a situation where you may have copied elements or other situations where you may not have elements properly assigned to stories.

You can 80 back and fine-tune later. Placement dialogs in Robot can be thought of as placement editors and the Nodes Dialog is no exception. You cannot exit a placement mode with the key. As you add nodes, you ean see them populate in the nodes table which gives great feedback on what you’re doing within the nodes dialog.

The layout provides a simple management of the interface to facilitate working with Robot. You will remain in the nodes placement editor until you change layouts. Be it a beam, column, or brace it is considered a bar. Modeling bars in Robot serves as not only geometry definition, but is also the confluence of several different. Generally speaking, letting Robot manage this is the best option, Member Name: This is an automatic Naming for members which will be used in member code-check verification and design to help you identify the member.

Using the ellipsis button to the right of name will allow you to adjust the naming scheme for the bars you are creating.

See the Bar Name section just below for more information Bar Type label: This label stores all properties regarding member ode checking: Eg. Section Label: This label stores information about the structural section type. Only elements that could be assigned the Bar ‘Type selected will be displayed in the section dropdown, This helps avoid, for instance, applying Timber calculation properties to a steel member and vice versa.

Discussion of using offsets will be dealt with in a future text. You can also type these variable names directly into the Name Syntax box but this is a convenient way to make sure that you have the variable syntax correct. Bar Type Labels in Robot are a means of creating sets of parameter settings which may be referenced by elements in the model.

This is very powerful in that members only reference a parameter set label so changing the parameters of the set the label all members which reference that label will have the new properties. We will discuss the particular settings for steel and conerete in their respective design sections. These code checking parameters are specific to the code you have selected in Taa.

In my case, I have selected AISC as my steel design code so my dialog indicates that in the title. If you are modifying a member type definition, you will be asked if you intend to overwrite the existing definition, Note that many members may already have this member type applied and by changing the settings, they will be changed for all members which have this member type definition label. In this dialog, you can configure new sections of all types and add them to the list of sections available in the Section dropdown in the Bars dialog.

If the section in the dropdown was a steel section, then the New Section dialog will open to the Steel Member configuration: I mention this specifically because the most important part of this dialog is down at the lower right, or 1 in this image.

This is where you tell Robot which type of section you intend to configure. The entire dialog will change based on this setting. Mf you: change Section type, then the new section type will be added to the list of section type labels but will not automatically populate in the Section dropdown in the Bars dialog. You first need to change the Bar Type dropdown to a bar type which applies to the new section you have configured.

We will deal with Standard Section types in this book, but it is worth noting that parametric, tapered, compound built-up sections can all be specified and analyzed. Family Filter: Select one of these options to reduce the number of families shown in the Family dropdown 6. Database: Allows you to select elements from various databases which you have configured in the Tao. This will change the options available under the Section dropdown below.

Ifyou want to use a C section as both a girt and a beam e. This advanced analysis and associated settings will be left to an advanced text. Closing the dialog will not save any changes and will not create the new section label for you to use in your project. If you wish to create several labels at once, simply pressing the Add button after configuring each will add them to the list of available sections.

Section Labels, similar to Bar Type labels are settings applied to bars. Sections are added to the project for use in modeling via the sections dialog. Using the ellipsis button next to the Section dropdown in the Bars dialog is a shortcut to adding a new section to the list of current sections in the project. Your default elevation may vary The template is preconfigured with this story. If you are not in the Plan tab, select that tab now. If you don’t see a plan tab, check that.

Make sure that the grid and ruler are on and snapping to grids is turned on: a. Your plan view should a. We may want to change those later but for now, they are fine.

This dialog is almost identical to both the Columns dialog and the Bars dialog. Our naming scheme will be the same as it was previously. Think of labels as keys into tables. Dil Nowsedit abet b. This is also available from Too. If you want to delete a support label, use the delete button mentioned in number Lb above. Creating a new support label You can either press the new label button Dito create a completely now label or you can double-click on any existing label to launch the configuration dialog and give ita new name.

We will cover Rigid and Elastic as other support types will require and understanding of nonlinear analysis techniques. Support Name: If you use the same name as a previously defined support you will be prompted to overwrite that support definition.

Doing so will affect any nodes, edges or planes which currently have this support type defined. Accept the default supplied name or provide your own custom name. Itis recommended to provide a name which will help you identify the support settings later e8 Pinned, XYRoller, ZSpringLOkft Fixity directions: These are all based on the project coordinate system for nodal supports however, Linear and Planar supports may be oriented relative to the member local coordinate system.

Node means that the X axis of the support will be aligned from its nodal position towards the node specified. No matter where you apply this support it will orient its X axis toward the node you specify no matter where it is in the project. Point is the same as node but is not bound to a node.

However, the X axis of the support will always align itself from the supported node toward the specified coordinate location. You can also select the label and press the new label button 3] which will simply open the definition dialog for the currently selected label.

Re-configure parameters as necessary and leave the name the same. You can simply type in your node or edge selection, you may make your selection graphically in the project or you can simply click nodes in the view to apply the support. We will take ch method in turn.

Click to apply: In the Support labels dialog, select the appropriate tab at the top Nodal, Linear or Planar.

You will only be able to apply support labels to the element type which corresponds to the tab you have selected. Next, select the label you would like to apply or the delete label if you wish to remove supports. Type in selection: In a similar way to the Click to Apply method above, select the appropriate tab Nodal, Linear or Area select the label you would like to apply.

Examples: 1. Next Click in the Current Selection edit control to indicate that you wish to create a selection and move your cursor out into the view. Notify All has no significance in this instance. Turn on node numbers using the toggle at the bottom of the view window 3.

You should now have a view which looks something like this! Uncheck UX and UY un-constrain movement in the x and y directions Notice that there are now two new labels in our Supports Dialog: a 15, Select PinnedFreeRotation and move your cursor out into the project Your cursor should change to a black arrow with a graphic of the support you are about to apply.

Go ahead and select several nodes by left:clicking on them. Go ahead and select several other nodes by box selecting. Select PinnedFreeRotation again and move the cursor into the view and click the lower edges of the other panels in the core wall. Close the Supports Dialog. When you are in the Release Label tool, the view will automatically switch to display codes but you can also do this manually.

First let’s take a look at the New Release Definition dialog. Unchecked means that it is to remain fixed. Note that if the label already exists, Robot will ask you if you want to overwrite the label definition. You now have two options. Similar to load application, these arrows are indicating the direction of the bar start to end which will be assumed by Robot for application.

If you move the mouse to the other end of the clement, the direction of the arrows will flip allowing you to apply the reverse of the label to the element. Release Label Codes and Symbols Robot displays information about the releases applied to bars with two different methods. The symbol ONLY indicates a release, there is no way to tell which displacements or rotations have been released.

Here is what it looks like in the project environment: A note about releases: Releasing degrees of freedom in the model can lead to model instabilities when it comes time to solve the system of equations. Here are some typical situations that you should be careful about.

In other words, Robot found a zero on the diagonal and introduced a slight stiffness which negates the zero: however, the model will very likely be incorrect in this state. Which degrees of freedom Robot chooses and why it chooses them is not immediately clear. If you choose to use releases in your model, it is recommended to begin with a few at a time, check the model can be analyzed then continue adding and checking.

The first place to begin looking at your model isin the displacements to see if there are any drastically unexpected displacements. Also be watchful for unexpected foree diagrams, and look out for unexpected torsion showing up along your members.

These are indications that there is something wrong in your model. Helpfully, when instabilities are detected and ignored during calculations, the Calculation Messages dialog will show, letting you know what.

Robot will manage this for you so even if you supply a number Robot will automatically replace it with the next in sequence. A great example of this might be a bridge crane load where you want to check the load at all support points but do not want them to all be applied at the same time. This can be the same as the Label or you can provide a more descriptive name to help you remember the usage. Now for the next one, change the nature to Live and check to see that Robot has switched the label and name to LL, if not, type those in yourself.

Finally add a WindNS case as well. You can model almost any conceivable type of structural loading in Robot from self-weight to drifted snow to harmonic loading and more. We will cover the basic types of nodal, bar and surface loads and leave advanced types to another text. Using the Load layout from the layout selector: The Load layout organizes the display to automatically show the load table and the load types dialog. Once you have configured your load cases, you typically will not need to use that dialog again however, it can be used to specify the current load case for load application.

That said, the load case selector on the selection bar can also be used so perhaps the most useful feature of the automated Load layout is positioning the load table nicely at the bottom of the screen so that you can watch the entries in the table as you apply loads graphically. You can also simply use the table to manually enter loads in cases where you have the same load to apply to many elements. You could also import loads from a spreadsheet if you have set the spreadsheet up to create information in a format similar to the loads table.

All this said, The Load Layout does not give you anything that simply opening the Load Definition Dialog would not do: the choice is yours. Select load case for load you intend to apply from the load case selector or in the Load Types dialog if you have that open 2. Select the type of load you wish to define H. Configure the parameters of the load to be defined in the corresponding load configuration dialog which opens after selecting the load type. You will then be returned to the Load Definition Dialog where you will select elements to which to apply this queued load.

Apply loads to elements: a, You may move the cursor directly into the project view and click elements to apply or b. If the Toad case displayed here is not the load case to which you would like to add a new load then change it from the case selector on the selection bar or by selecting, it in the Load Types dialog.

Detailed descriptions below. Node: loads or displacements acting at a single point in the structure b. Surface: Loads on planar surfaces B.

Selfweight and mass: applying self-weight for whole or part of the structure, lumped masses, body forces and centrifugal forces on elements. You may type your selection, copy paste your selection, use the selection dialog, or manually select elements in the project. This edit control is intended for use with the Apply button below. May have angle of application specified. Intended for use in conjunction with shell and volumetric elements.

Bar Force Concentrated force or moment and angle of action at a particular point along a bar. Loads acting eccentrically to the member may also be defined with this tool. Dilation Dilation: Load is a lengthening or shortening of a member. Planar load Planar load is a method of applying loads to multiple members at once. Load magnitude can be specified at each point to create a linearly varying load.

For snow drift loads on rectangular areas use the Planar 3p Load on Contour below. Can configure both a uniform plus portion that varies with depth according to a unit weight per unit volume setting. May be oriented with respect to any of the three axes. Specified points need not fall within the defined contour. Use this type for applying snow drift loads. Ke Added Masses – Bars Define additional mass for linear elements along their length. Enter the magnitudes of the concentrated nodal force components in each of the three global axes X, Y, and Z.

Next specify the concentrated nodal moments about each of the global axes and last define an angle of rotation about the axis at which the forces act relative to the specified axis.

Each angular measurement is an amount of rotation about the specified axis. Click to apply: When you move your cursor out into the project area, the cursor graphic will change to an arrow with a graphic indicting a nodal load. You can simply begin selecting nodes in the project environment by clicking them directly when this cursor is active.

The load is applied as. Once you have done this, the click-to-apply cursor does not like to come back. Hach angular measurement is an amount of rotation about the specified axis. Decide if this load should be projected or not. It should be added that this consideration ignores any rotation of the load. If you choose to use rotation of the load, be careful about using projection.

Your model, however, will still appear to have a uniform load applied at the eccentric application point. Creating a Uniform Load in the Project: 1. Click to apply: When you move your cursor out into the project area, the cursor sraphic will change to an arrow with a graphic indicting a uniform or planar load. You can simply begin applying the load to bars in the project environment by clicking them directly when this cursor is active.

Once you have done this, the click-to-apply cursor docs not like to come back. You must decide if X, Y, and Z refer to the global axes of the project. The number of value fields here will directly correspond to the selection made in number 1 above.

Current units are displayed for reference at the top of the column. Projected loads are often used in snow loading for an element. It should be added that this consideration ignores any rotation of the load, If you choose to use rotation of the load, be careful about using projection as the results may not be what you would expect.

All bar loads and surface loads will use this same icon b, You can simply begin applying the load to bars in the project environment by clicking them directly when this cursor is active. Notice that hovering near one end of the beam or the other results in two little arrows along the length of the bar. This is indicating the direction of the x axis of the bar for purposes of applying a trapezoidal load.

Using the Selection Dialog: You can also use the Selection Dialog to build a selection for applying your loads. Chain Selection: a. The last checkbox option controls how Robot deals with subsequent changes to geometry. If left: unchecked, Robot will continue to think of these bars as a single element where this oad is concerned. Ifchecked, each bar will be treated independently and will maintain the values of load at its ends upon modification.

See the Robot Help files for graphics illustrating this. This can be incredibly important: Member designs and code checks are performed at only specified locations along the length of a member. As you can see from the steel member verification results, the calculated max moment for this member is 0. It will not provide any diaphragm action. Claddings are planar elements which may be created in any orientation.

Once created they provide a distribution element which can take planar loads and distribute them to model elements in either a two-way or one-way distribution.

Claddings have local coordinate systems which dictates which directions the load is distributed. You can view the local coordinate system for each cladding, modify it and also display the current distribution options selected for the cladding object. This will laddings Dialog as shown here: 1 Object Number: Robot will automatically pick the next available clement. If you choose to specify one and that element already exists in the project, Robot will ask you if you want to re-define it.

Options are: a. Two-way: loads are distributed with a trapezoidal distribution to members co-planar with the cladding element in both the cladding local X direction and the cladding local Y direction. Circle: Simplified definition by three points 4 Geometry section expands to allow configuration of the vertices of the cladding.

Te will change depending on the style of cladding geometry you have selected in 3 above. Contour, Rectangle, or Circle. While it is possible to create a non-planar cladding, doing so will not allow you to apply nor distribute loads. Current vertex list? For buttons as you click in the project environment, you can select back and forth between these options for each edge you wish to create thereby stringing together linear and are segments in order to specify exactly the cladding configuration you desire.

To use this interface, right click in the spreadsheet to insert a new row and configure the parameters. Rectangle: This is a simplified version of the contour definition above and will likely be the most frequently used. Changing the Definition Method will discard your current vertex Selecting Rectangle will reconfigure the Geometry section as shown You can type in the coordinates of three points defining the rectangle. The first two points define the first edge and the last point merely defines the distance perpendicular to the first selected line and potentially the inclination if a 2 coordinate magnitude is specified by manually typing in coordinates or snapping to elements in the project.

Circle: Requires the definition of three points that lie on the circle. You may manually type in the coordinates or select the points in the project environment. You may create a sloped circle by either manually specifying a z-coordinate or snapping to an elevated piece of geometry in the project. If you are clicking in the project to define points simply selecting the last point for rectangle or circle will finish the definition and add the cladding.

Loads are distributed along the X and Y axes so the orientation is very important information. Here the two-way distribution cladding has four areas of load distribution to supporting members.

There are only four members at the edges of this cladding You can also see the automatically generated loads applied to the beam members at the edges of the cladding resulting from the load distribution by the cladding element to the supporting beam elements. Placing the cursor in the edit control, you can click two points in the project environment to specify this vector or you can manually type in a direction vector referenced to 0,0,0. Robot will align the X axis with this direction vector.

Which will launch the Load Distribution Dialog This is another Robot Label dialog: the three available options for distribution are labels which can be applied to cladding elements by selecting the label you want to.
