NUMERICAL STUDY ON THE SHEAR RESISTANCE OF COLDFORMED STEEL SHEAR WALL WITH STEEL SHEATHING

Shear wall panel as one of the primary lateral load resisting components, has been extensively used in lightweight framing of low and mid-rise residential constructions. In this paper, the shear resistance of cold formed steel stud walls with single sided steel sheathing has been investigated under monotonic loading by finite element analysis. The numerical modelling of shear wall taking into account geometric large deformation and material nonlinearity has been conducted using finite element method .The results obtained from FEM have been verified against the available experimental results. Using finite element analysis, parametric study is carried out considering height-width ratio of wall, stud and sheathing thickness and screw spacing in order to obtain the shear carrying capacity of the wall. The numerical results have shown the good seismic performance of cold formed steel stud walls with steel sheathing.
