SCIA Engineer BIM link for steel connection design (EN)

Comment activer le lien

• Téléchargez et installez la dernière version de IDEA StatiCa
• Vérifiez que vous utilisez une version autorisée de votre solution MEF/BIM 

IDEA StatiCa intègre les liens BIM dans vos solutions MEF/BIM lors de l'installation. Vous pouvez voir le statut et activer autres liens BIM pour des logiciels installés aussi plus tard dans l'outil d'installation des liens BIM.

Veuillez noter qu'il faut des étapes supplémentaires pour activer des liens BIM de quelques solutions MEF avec IDEA StatiCa.

Ouvrez IDEA StatiCa et allez à l'onglet BIM et ouvrez l'outil d'installation des liens BIM (Activation du lien BIM...).

Une notification avec le texte « Voulez-vous autoriser cette application à apporter des modifications à votre appareil ? » peut apparaître. Dans ce cas, veuillez confirmer avec le bouton Oui.

Le lien BIM pour le logiciel sélectionné (si trouvé) sera installé. L'écran vous montrera aussi le statut d'autres liens BIM qui peuvent être déjà installés.

How to use the link

Download the attached project, open it in SCIA Engineer, and run the linear analysis to get the internal forces over the structure.

The BIM link is automatically integrated. You can find it in the top ribbon under Design -> External tools -> IDEA StatiCa. 

Or run the "IDEA StatiCa" command in the top command line. 

Both of these options will open the Checkbot application.

Select the New option with project type Steel and design code EN. Then select Create project.

The new Checkbot project is ready to import connections from SCIA Engineer.

In SCIA Engineer, select one of the inside columns with bracing making sure you also select the lowest node.

Import

Then in Checkbot select Connections.

This will import the column and its load effects into Checkbot - with the same coordinates, orientations, and section sizes as per the FEA/BIM model.

Please note that your node and member numbering might be different.

Please note the 3D workspace is designed to show an overview of the imported structure and not a detailed view of the actual connections.

For more information on Checkbot, see here.

For several FEA/BIM solutions, you can also import multiple connections into Checkbot in the same manner as above.  Instead of selecting one node and the connected members, you can select several nodes and members using the selection methods within the application.

We recommend not importing all of the connections at the same time but building up the connections incrementally.

Geometry

In the list of project items under Connections and with a connection highlighted in Checkbot you can either right-mouse click and select Open or click the ribbon command Open to start designing, code-checking, and reporting.

The settings of members are taken from the original FEA/BIM application. You can, however, change the section size of any member on the main Checkbot screen, but this will break the link with FEA/BIM application in this session unless it's synchronized again.

The imported connection is opened in the IDEA StatiCa Connection application.

You may see none or different Load effects from your preferred FEA/BIM* solution depending on how the load case combinations have been defined.  By default, IDEA StatiCa will choose the most critical for code-checking purposes. (* Some BIM solutions are not able to store the load case combination results)

For more information on Load effects see here.

Design

We are going to be using a single bolt connection for the diagonal brace. For this type of connection, we must also change the Model type of the brace member to N-Vy-Vz. Select the brace in the list of Members and modify the Model type in the drop-down list.

We are going to use the Connection Library to generate a connection. Select Propose and IDEA StatiCa will put forward possible solutions for the current geometry.

Connection Library shows you the possible solutions for the current geometry. Choose the template offered and press OK.

Accept the proposed values for the bolts and concrete block and press OK.

This is what the initial connection looks like.

With these default parameters for the Base plate.

These are the parameters for the Connecting plate.

That completes the design of the connection for the column base plate with a diagonal brace.

Code-check and Report

Now run a code-check using the Calculate icon in the CBFEM panel from the top ribbon.
Within IDEA StatiCa Connection, you can carry out many different types of analysis and code-checks. For more information, please see here.

The results might not be acceptable. In this case, the anchors fail because of their low design capacity.

You can go to the Check tab to review the results and take a closer look at the anchors by expanding the calculation using the '+' symbol.  You can see that the anchors are failing in tension in the concrete block.

We must optimize the design to find the passing solution. Go back to the Design tab, highlight the base plate operation, and change the Anchoring length to 200 mm and the concrete block Offset to 300 mm then run the analysis and code-check again.

Once the code-check is finished in the Report tab, you can create the report containing results and diagrams for your connection model.

The report can be printed or saved in several formats. For more information, please see here.

Save and Exit this connection back to Checkbot.

In Checkbot, you will see a green tick next to the connection. This means that the connection is valid and has passed all code-checks. In the Connection panel, you can also see a representation of the connection and a summary of the code-check results.

If multiple connections are present in Checkbot, then each must be opened, designed, and code-checked.

In the example below, you can see that both baseplate connections have passed their respective code-checks whilst the remaining connections are yet to be validated.

You can continue with the design of additional connections - See how to model the roof connection with braces

Synchronisation du modèle

De temps en temps, il y a des modifications de votre modèle MEF/BIM, par exemple une taille différente de section d'un élément ou des charges différentes. Il est possible de les synchroniser entre Checkbot et le modèle MEF/BIM.

Il y a deux alternatives :

• Synchroniser l'Élément actuel (si un ou plusieurs assemblages sont sélectionnés)
• Synchroniser le Modèle structural importé entier

Pour vérifier cette fonction, vous pouvez changer la taille ou forme de section d'un élément dans votre application BIM/MEF ou modifier un cas ou combinaison de charge, etc. : changez les poteaux pour une section plus petite. N'oubliez pas de réanalyser le modèle MEF.

Dans Checkbot, sélectionnez les attaches conçues (il peut y avoir plus qu'une) et puis Synchronisation au panneau Élément actuel.

Le projet dans Checkbot sera actualisé, la conception d'attache sera enregistrée mais les résultats ne seront plus valides. Vous pouvez voir que le poteau est actualisé – avec le même changement qu'au modèle MEF.

Il faut seulement vérifier les attaches en surbrillance encore une fois en sélectionnant Calculer au panneau Élément actuel. Veuillez noter que des changements plus significatifs du modèle peuvent exiger des étapes de validation supplémentaires pour les attaches affectées (comme ci-dessus).

Si les attaches ne donnent pas de résultats désirés, vous pouvez les rouvrir pour optimiser la conception (renforcer-les si elles échouent la vérification ou alléger si l'utilisation est trop basse).
