IDEA StatiCa Tutorial - Revit AISC

Welcome to IDEA StatiCa tutorial. This tutorial will show how to activate and use the link between Revit and IDEA StatiCa Connection.


1 How to activate the link 2 How to use the link - Frame joint

5 Update - Frame joint


1 How to activate the link

We have to follow these steps:

  • Install Revit first - make sure you are using a supported version of Revit – updates are published in the BIM section
  • Install Robot Structural Analysis
  • Install Structural Analysis Toolkit for Autodesk Revit

After installation of both programs, run IDEA StatiCa and start with the item BIM.

In the BIM wizard continue with the item Activate your Bim Link... During the process notification "Run as administrator" appears. Please confirm with the button Yes.


Select your version of Revit and click the button Install. The process of integration will start.


2 How to use the link - Frame joint

Open the attached project in Revit.


Revit is a kind of unique tool for engineers because in Revit model can be stored geometrical and analytical model together with the analysis results. IDEA StatiCa Support team defined geometrical model of the steel structure, defined analytical data (loads, load effects, combinations, etc.), imported it to the FEM analysis application and performed the analysis. In the next step was the analysis results imported back to the Revit model. Let's check out if the results are available.

We will double click on the Analytical Model view in the Project Browser tab. By this the analytical model is shown. Also, the changing scale of the visualized items to 1:100 is handy. Choosing Results Explorer command in the Analyze tab is the next step.


The window Results for Analytical Model is shown. We will choose the Analysis results and Com1(which represents the Combination 1 defined in advance), then Moments My from the Results for Members group. Proceed with Apply. The FEM analysis results are available and can be explored.


Let's get back to the 3D model view and the left frame joint from the first frame must be found. For better visualization the Hidden Line model view is recommended.


Let's proceed with starting the IDEA StatiCa Code-check manager from IDEA StatiCa tab.


Code-check manager is tool for exporting of the connections, opening items created by the export, synchronizing changes in the model, etc. We will go thru some of the commands further in this tutorial. Now let's use the command button New and AISC command. By this step the BIM import process will start.


In the first step we skilfully choose the haunched frame connection shown in the picture below by the left mouse button click.


In the second step (this step is optional) the other predefined connections can be assigned to the import. We want to choose two more parts of the whole frame joint, connection of the bracing to the column (part 1) and connection of the beam to the column (part 2). We confirm the selection by the Finish command (3).


3 Design - Frame joint

Automatic data transfer is finished and IDEA StatiCa Connection with the generated project is launched. All members and load effects were added automatically.


One weld definition must be changed. Let's rotate the model in a way that the weld under the column cap can be seen and click on it with left mouse button. The right manufacturing operation will be choosen and it's properties shown in the right part of the window. We must chose the double fillet weld.


4 Calculation and Check - Frame joint

We can calculate the analysis right in the Design tab by the Calculate command. After the performed analysis let's change the tab to Check and set the Equivalent stress, Mesh and Deformed model view. The results can be explored easily. We are now satisfied with the connection design and the data should be Saved. Now let's close the project window.


And we are back in the Revit with opened Code-check manager. Let's check out what can Code-check manager offer.

In the list of the Project items can be found the exported, designed and code-checked frame joint, information about the assessment is provided also.


5 Update - Frame joint

We can take advantage of the Update function. We can make changes in the Revit model connection and by one command update the IDEA StatiCa Connection model. Let's take a closer look on that.

Let’s say we need to change some entity in the Revit connection model. For example, thickness of the gusset plate for the bracing member. Double click by the left mouse button on the connection entity will open the properties dialog.


In the connection properties dialog let's change Gusset plate parameters. For the Thickness will be right value 9.525 mm (3/8" in imperial units).


Now in the Code-check manager by the command Synchronize, the application will load the changes and update the Connection model.


In a while the IDEA StatiCa Connection window will open with the updated frame joint. Let's check the thickness of the gusset plate. Hoover mouse cursor over the gusset plate in the 3D scene, the gusset plate will be highlighted by the yellow color and brief information will be printed in the left bottom corner of the 3D window. The change in the Revit model was brought to IDEA StatiCa Connection model.


Before closing the project window we need to change the weld under the column cap to Double fillet weld again (Weld1) and Save the project. Then it can be closed.


6 - How to use the link - Bracing

Now we already know how to use the Code-check manager. So let's perform import for another joint. We will locate the X bracing joint to the column in the Revit model and export it by the New AISC command.


In the first step of the import procedure we will choose the connection of one bracing member.


In the second (optional) step we will chose other connections which are present in the same node according to the picture below.


7 Calculation and Check - Bracing

We can calculate the analysis right in the Design tab by the Calculate command.


After the performed analysis don't forget to Save the data and close the window.


The Code-check manager contains two project items now. Each of them can be easily located in the 3D model by clicking at the gray square. The joint and it's entities is highlighted in the 3D model by the blue color.


Let's check out our previously exported frame joint.


8 Update - Bracing

Let's take and advantage from the commands in the Code-check manager to update the model. We are going to do a different approach. At the first step, the change in the bracing joint must be performed. Let's change the thickness of the gusset plate. For the Thickness will be right value 9.525 mm (3/8" in imperial units).


In the second step, let's explore commands in Code-check manager. If the mouse cursor will be hovered up on the Calculate command, the tool tip will help us to understand what will happen. The Calculate button will start the process which will Synchronize and calculate the current item and provide the new set of the results. Let's choose the Calculate command.


The synchronization, calculation was performed and the new set of results was provided as the info for the current item.


The other commands such as Delete and Calculate all can be used to manage project items also.
