Reinforcement of concrete slabs

Hello everyone,

I have one problem, refers to the reinforcement of concrete slabs.

In the settings for the steel diagram (stress-strain), I set the limit strain (e_uk) to be equal to 20 mm/m.

When I perform the reinforcement, the strain in the steel will be greater than 20 mm/m.

Thank you for your understanding as my English is not the best.

Best regard
