Steel joint design resistance (AISC)

Learn how to how to use software IDEA StatiCa to model, design and check a structural steel joint and calculate Joint design resistance.

1 New project

Start with launching the IDEA StatiCa Connection and open the project file (or below this tutorial) for this tutorial.

Since you work under the AISC code, make sure to set imperial units (see How to change the system of units).

2 Check

You start the analysis by clicking Calculate in the ribbon. The analysis model is automatically generated, and the calculation is performed.

You can see the Overall check displayed together with basic values of check results.

3 Joint design resistance

You have to Copy the project item first to save the previous work and change the analysis type to DR (Joint design resistance) for Connection 2.

Now you can calculate the Joint design resistance analysis by Calculate command in the top ribbon.

4 Check

Let’s proceed to the Check tab and Joint design resistance tab in the result tables. The application gives us the factoring percentage of the load to reach joint design resistance. The figure for the percentage increment load to strain dependence is also provided. The values of the Design load and Design resistance are provided to visualize the results.

We have designed, code-checked, and calculated the joint design resistance of the connection according to AISC.
