Hey everyone

I’m struggling with getting proper results out of sofistik.

There are nice examples of non-linear calculations to calculate with uncracked concrete, which gives also nice results as shown in the picture:

When I try to make my own model: a simple supported concrete reinforced beam, loaded uniformly distributed. And I want to calculate the stresses in the concrete and the reinforcement. I added my teddy code in attachment.

Can someone help me how I properly can calculate the stresses in the concrete and beam, and also how I can design such a cross-section?
