Abstract

In this paper, the effect of openings on global performance of Cold Formed Steel Shear Wall Panels is investigated numerically using the ABAQUS software. A benchmark model is first validated in terms of lateral shear capacity and nonlinear behaviour of the CFS-SWP. The failure mode of the CFS-SWP with opening is identified and validated. Subsequently, a parametric study on the effect of size and position of openings is conducted, in which the opening position is found to have a significant impact on the CFS-SWP performance. The benchmark model can be used for design purposes to evaluate with good accuracy the reduced ultimate strength of individual CFS-SWPs for any size and position of openings.
