Abstract

In the latest North American Specification for the design of cold-formed steel structural members AISI S100-16, an empirical approach is specified to design beams with web holes in shear. Recently, a Direct Strength Method (DSM) of design for shear for perforated beams with the aspect ratio (shear span / web depth) of 1.0 has been proposed. This paper presents a comprehensive review of the proposal and an experimental validation using a test series on beams with the aspect ratio of 2.0 and with various square and circular web opening sizes conducted at the University of Sydney, and other experimental data collected from the literature. As a result, it is proven that the earlier proposal reliably predicts the shear strength of perforated structures with centrally located square and circular web holes and with an aspect ratio up to 2.0.

New Proposals for the Direct Strength Method of Design of Cold-Formed Steel Beams with Holes in Shear

In the latest North American Specification for the design of cold-formed steel structural members AISI S100-16, an empirical approach is specified to design beams with web holes in shear.
