New design methods for calculating the nominal web crippling strength of the CFS C-sections and Z-sections subjected to End- One-Flange loading and Interior One-Flange loading conditions were developed and verified by the experimental results. ASD Safety and LRFD resistance factors were calculated according to the AISI standards. ABAQUS is used as the main tool for calculating the critical elastic buckling load of the C-sections and Z-sections. The research proves that the concept of Direct Strength Method works for the web crippling strength of CFS members. Further analysis is needed to allow the Direct Strength Method to address other member types such as I sections, hat sections, etc., in web crippling.
