      Hello, I would like to know how we can modeling bracings (X, V or K) in way that the element are only on tensile (or compression) behavior. How are you doing this?


      Best regards

      Please reply with the version of ANSYS you are using.


      You must use only 1 Link element per brace and set the Behavior to Hard to prevent additional elements being used on these 12 lines.

      Hello Peter,


      I can't have the Von mises stress for the beams and columns.


      Is that normal?

      Hello Maxime,


      Sorry for the delay in replying.


      Yes, you don't get von Mises Stress plot for beam elements.


      On Solution you can Probe > Beam > Axial Force and Shear Force.


      On Solution, right click to Insert > Beam Tool.  Then in the Beam Tool, right click to Insert > Maximum Combined Stress.  This is the Axial Stress combined with the Bending Stress.  You can also just plot Direct Stress = Axial Stress.
