How do I adapt the strength of steel materials?

The Eurocode specifies different yield and ultimate strengths for each steel material, depending on the thickness of the plates. This is why in each steel material you will find the option thickness range, which opens up a menu that defines the yield and ultimate strengths for a range of plate thickness. These are the values that will be used in the steel code check and not  the values shown just above this thickness range. Therefore if the user wishes to adapt the yield or ultimate strength of a steel material in SCIA Engineer, it must be done inside the thickness range:
