Abstract
Thin-walled channel members subjected to shear are commonly perforated with web openings to provide access for building service systems. The changes in the stress distribution due to the presence of holes can cause the changes in the critical buckling load and the overall strength of the perforated members in shear. Recent research by S.H. Pham has provided buckling solutions based on Finite Element Method for determining the shear buckling loads of channel sections with web holes with shear aspect ratio up to 2.0. However, the research only focused on square and circular holes. With the same methodology, this paper provides a buckling solution for perforated channel members with elongated web holes in shear. FE models were constructed to generate the elastic buckling loads with a very wide range of hole dimensions. The assumptions about the stress distribution from the previous studies were also utilized in this study. A dimensional transformation is also proposed in this paper.
