Hello. Does anyone have a book or training material for calculating the critical force and critical bending moment for steel trusses and beams due to sheet metal stiffening ? It is probably said in EUROPEAN RECOMMENDATIONS FOR THE APPLICATION OF METAL SHEETING AS A DIAPHRAGM. STRESSED SKIN...
It depends on the class of concrete, moisture, dry concrete, age of concrete at the time of loading and type of cement used. Range between 1 and 4.3 if it is loaded after 28 days. I refer to the EC 2 Figure 3.1.

Hi, I would like to discuss the verification of the stability of truss when the top bar is secured with trapezoidal steel sheet.
Verification methods are, for example, in EuroCode 3 1-3 and ECCS TC7 TWG 7.5.
Has anyone had contact with this issue and has a computational example?
Best regards!
