Buckling analysis of a steel connections (EN)
1 New project
Let’s launch the IDEA StatiCa Connection application. Create a new project by selecting a template closest to the required design and fill the name and the description of the project. After choosing the required properties, confirm by Create project.
Start with the modification of the joint geometry. Right-click on the web of the continuous beam opens the context menu with all available actions for the beams. Use the Plus button to add a new cross-section.
Choose the I profile and the HEB category, and HEB180 cross-section.
Proceed with the change of cross-section on the perpendicular member. Again, use the right mouse button, click on the web and choose Plus to add a new cross-section. Select the SHS 80/80/5 cross-section.
Now you can adjust the properties of beam B1 with a squared cross-section. Follow the picture below.
3 Load effects
Now define the manufacturing operation. Start with the right mouse button and click on the Operations row in the tree of entities in the 3D scene. Choose the New operation command from the context menu.
Choose the Connecting plate operation in the tab of all available manufacturing operations.
And proceed with choosing the desired bolt assembly, the M16 10.9.
Now define the properties of the connecting plate. Follow the values in the picture below.
5 Calculation and Check
Now switch to the Check tab at the top of the ribbon and then start the calculation of Buckling analysis under the Calculation command button.
By clicking on each row in the tab of critical buckling factors, you can browse the deformed shapes in the 3D window and analyze them visually. The critical buckling factor can be compared with the code requirements. Usually, buckling can be considered safe in case of critical buckling factor values greater than 15 for global buckling and 3 for local buckling.
At last, go to the tab Report. IDEA StatiCa offers a fully customizable report to print out or save in an editable format.
You have designed, optimized, and code-checked a structural steel joint according to Eurocode (EN)
