• TITLE: A Simplified Procedure for Prediction of Ultimate Strength of Beam-Column Channel Sections

  AUTHORS: Osama Bedair

  KEYWORDS: Channels, Steel Design

  JOURNAL NAME: Engineering, Vol.3 No.10, October 21, 2011

  ABSTRACT: A design procedure is presented to estimate the load carrying capacity of beam-column channel sections. A reduced cross-section is used to compensate for the reduction in the post-buckling stiffness. The non-linear stress distribution acting on the entire channel width is replaced by simplified linear distributions. Using this simplified concept, the maximum stress in the post-buckling state, is assumed to be carried entirely by both edges while the central region of the channel remains unstressed. Thus a fraction of the channel section is considered in resisting the applied loading. This approximation enables the structural engineer to deal with a simplified stress distribution to compute the ultimate strength instead of the non-linear one.
