Modification of the steel stress-strain curve

Hello all!

Could you please tell me one thing. Does Sofistik modify the steel stress-strain curve or I have to do it by myself? I mean the red part of diagram on the picture below.

Thank you!

Sofistik models the complete stress-strain curve according to the selected design code.
E.g. S355 steel:

You can use a bespoke stress/strain curve with the command SSLA.
Check the report output from AQUA to see what you have.

Of course a detailed stress-strain curve is only useful if you use it (e.g. non-linear calculation)

Thank you so much for responding!

Actually I meant tensioned concrete between cracks. And my question is about modifying the reinforcement diagram. Do I need to modify the diagram by myself using SSLA? Or Sofistik does it if I use CTRL CONC V3 and V4?

Best regards,
Helen

Ctrl conc should be enough.

Great! Thank you so much
