Rigid links

I am working on a composite bridge. I need to connect the girders with the bracing system with rigid links. I tried to use spring cross sections with high stiffness but it does not work properly. Alternatively I use a circular cross section with high rigidity but I would prefer to use the first option. I appreciate any help.

Hi, the best method is to create a standard beam with a cross section with a material with a high rigidity.

Perfect, thank you!
