The Influence of Web Holes on the Behaviour of Cold-Formed Steel Members: A Review

The use of cold-formed steel (CFS) members in structural engineering has been on the increase recently due to a wide range benefits. placement electrical and/or plumbing installations within floor or wall thickness requires that are being manufactured with holes along web, inevitably affecting their resistance. This article aims at providing useful and comprehensive overview existing literature regarding CFS web holes. Experimental numerical research subjected pure compression, bending, crippling shear is outlined discussed. Although these types date back early 1970s, greatest progress field was achieved during past 15 years; hence, mostly conducted this period addressed. Additionally, design proposals summarised for each aforementioned stress states. A brief description main concepts presented four principal codes, as well solution methods predicting global, local, distortional buckling modes, also presented, aiming collect accessible up-to-date knowledge identify areas were modestly covered by previous research.
