I’m trying to evaluate the stiffness of a shell structure, using pre-bent elements (timber or metal) attached together. The goal is to simulate the bending of the strips, which is supposed to give stiffness to the structure, and then apply a point load to see how the structure would deform.
My main issue is finding a way to simulate the added stiffness generated by the bending of the strips. So far, I tried using the component “initial strain” but I feel like it isn’t working because whenever I disable it, nothing seems to change.
If anyone could have a look at the definition and help me solve this issue it would be great.
