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
