Web Crippling Strength of Steel Deck Subjected to End One Flange Loading

Cold-formed steel deck profiles are extensively used in building construction due to their versatility and economy. Web crippling is one of the failure modes of these multiweb profiles. The provisions for web crippling contained in the 1996 AISI Specification for the Design of Cold-Formed Steel Structural Members are believed to be conservative for multiweb deck sections. They are based on unfastened specimens and are limited to the use of decks with certain geometric parameters. The unified web crippling equation of the 2001 North American Specification for the Design of Cold-Formed Steel Structural Members is also limited to certain geometric parameters. Although new web crippling coefficients for different load cases and different end conditions are contained in the specification, coefficients for the unfastened configuration in the end one flange loading case were used as a conservative solution for the fastened case because there are no test data available in the literature that are applicable to mul...
