COLD FORMED STEEL STRUCTRUE

[WiQi]

HI
how the cold formed steel design is different from the Hot rolled steel design?
is design of cold formed steel structure on SAP2000 ok or some other software should be used?
any other good software for CFS design?
how do we apply temperature on the CFS structure.i have CFS model is sap2000 but when i apply temperature loading by gradient of even 10 degrees without joint pattern, str members fail drastically.do i have to apply temprature loading with joint pattern loading?
should i apply temp loading only on roof and walls or have to apply on frame members also which are at the periphery?


Regards

If you want to design CFS members and their cross sections - look into the program CUFSM which uses the Direct Strength Method.

CFS design using the effective width method is similar to hot rolled sections, but a little different to account for the fact that they are thin-wall members...
