摘要

The 1996 Edition of the Americal Iron and Steel Institute (AISI) Specification for the Design of Cold-Formed Steel Structural Members does not address the limit states of shear lag, staggered holes in a tension member connection, and limited elongation of a bolt hole prior to ultimate bearing capacity. Research at the University of Missouri-Rolla has examined the behavior of bolted connections in cold-formed steel flat sheet, angles and channel members subject to tension load. Based on the findings of the UMR research, additional design provisions were developed. The UMR equations provide for a design approach for cold-formed steel members and connections that is similar to the design approach used for hot-rolled steel design in the United States.
