IDEA StatiCa Tutorial – Robot Structural Analysis BIM link

This tutorial will show how to activate and use the link between Robot Structural Analysis (RSA) and IDEA StatiCa Connection.

Activate the link Use the link Update the project

1 How to activate the link

  • Install the latest version of IDEA StatiCa, get it in the Downloads
  • Make sure you are using a supported version of RSA – updates are published in the BIM section

IDEA StatiCa automatically integrates the BIM link into your CAD/CAE software during its installation. You can check the status and activate more BIM links for later installed software in the BIM link installer.

Open IDEA StatiCa and navigate to the panel BIM and open the BIM link installer. A notification "Run as administrator" may appear, please confirm with the Yes button.


Select the software to integrate the IDEA StatiCa BIM link, click the Install button and check the Installed status.


2 How to use the link

In Robot Structural Analysis, the link should be automatically integrated. We can find it in the top ribbon under Add-Ins – IDEA StatiCa – Connection. This button will open the Code-check manager.


For the first exported connection, select it with all the corresponding members in Robot and open the Code-check manager (Add-Ins – IDEA StatiCa – Connection). Create a New connection and select the code you want to use. In this example, EN was chosen. An export wizard opens automatically.



We select the bottom column member, set it as Bearing and merge column members by OK button. We continue with Next button.


We can adjust the properties of the load cases here. Then we continue with Next.


In this step, we can see all the combinations with corresponding load cases created in Robot Structural Analysis. We can also create a new combination. We don’t have to change anything here.


In the last step, we can check all the combinations that will be considered for export to IDEA Connection. To speed up the calculation in this tutorial, we erase all the combinations except the most critical ULS100.


Finish the BIM wizard.

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


3 Geometry

The geometry of the connection has been imported. We can see all the members with the proper orientation and cross section.


4 Load effects

The load (combination ULC100) has been imported from Robot Structural Analysis.


5 Design

We will define a set of manufacturing operations to model connections between members.

We can start by the connection of horizontal member B411. We use the right-click on the member to open the menu. There, we select Connect to… option.


To connect it to the vertical member B1706 (column), we select it by the mouse click.


That opens the list of predefined templates. We select the end plate option.


And we define the default bolt class and size.


End plate EP1 has been created and we can edit its parameters.


To connect to diagonal, we add a new Operation from the top ribbon – Connecting plate.


CPL1 was added and we edit the parameters.


The shape of the gusset plate can be adjusted in Editor – Gusset plate. We add a bevel on the corner 2.


To copy this operation on the bottom diagonal, we use Copy option from the ribbon above the table and change the member to B1640.


The third diagonal will be connected by a Stub. We add this operation the same way we did before.


We change the default values of the operation STUB1.


Now, we will add two Cuts.


This operation will cut and weld the stub to horizontal member.


We copy CUT1 and change the Cut by to B1706.


The last added operation is the Cleat.


We change the parameters of CLEAT1.


The profile of the cleat is selected from the library.


The connection has been designed. We can proceed to the code check.


6 Check

Nonlinear analysis is started by icon Calculate button in the top ribbon. Analysis model is automatically generated, the calculation is performed and we can check results. We can see directly the overall check in the table in left part of the 3D scene.

All values can be checked in detail in the tables and 2D window. For example, to display check of plates, we select the corresponding tab. We can also activate the icon Equivalent stress and Mesh from the ribbon.


7 Report

IDEA StatiCa offers fully customizable report to print out or save in editable format.

8 How to synchronize model

Sometimes, it is necessary to edit the original model in Robot, e.g. change the cross-section of a member in the joint.

In this case, save the project and close IDEA StatiCa Connection. All joints exported from RSA project to IDEA StatiCa are kept in Code-check manager for later updates and you can see them in the list together with summary of the analysis (if available).

Close the Code-check manager.

Code-check manager is a BIM tool to export and synchronize connections from other programs. It is launched directly in the 3rd party applications via a command/icon.

Synchronize - IDEA StatiCa detects changes in already imported entities (changes in thickness, changes in cross-section, modification of properties of welds, bolts, etc.) and updates the project in IDEA StatiCa Connection.

Modify - IDEA StatiCa imports the whole joint again with modified topology (different number of members, new entities, etc.).

Calculate - Synchronize and calculate current item and provide a new set of results.

Calculate all - Synchronize and calculate all items and provide new set of results.


Kindly be aware that IDEA StatiCa syncs with a model of the 3rd party application, not the other way around. If we add operations in IDEA StatiCa and then use the options described above (Synchronize; Modify; Calculate; Calculate all), the additionally added operations will be deleted.


Let’s present an example of managing changes in the models.


Let’s say we need to change the cross section of beam 351. We substitute HFSHS 180*180*12 by HFSHS 120*120*8. We have to confirm the change of database of structural data.


We open the Code-check manager again (Add-Ins – IDEA StatiCa – Connection). We update the model by the Synchronize button.

The export wizard is opened again. We merge the columns by OK button and set them as bearing. We press Next.

To save some computational time, we select only one load case (ULS100) in the last step.


The export of the updated project is finished and we can see that the cross section of the member B351 was changed.


We can edit the STUB1 operation and recalculate the project.
