Abstract
Cold- formed steel sections are used as wall studs (or) floor joists,rafters and trusses,such sections include web holes for ease of installation.Cold-formed steel design codes does not consider the effect of such web holes.In this paper,combination of theoretical tests, experimental tests and finite element analyses are used to investigate the effect of such holes on web crippling under concentrated loading conditions.A good agreement between the theoretical, experimental tests and finite element analyses was obtained.The finite element models are used for the purposes of parametric study on effect of different size and position of web holes.The main factors influencing the web crippling strength are,the ratio of the depth of hole to the depth of web.In this paper recommendations for web crippling strength reduction factors are proposed.
Keywords- Cold Formed Steel, Finite Element, Cripple Strength, Steel Design
