Abstract
The cold-formed steel framed shear wall sheathed with steel sheets (CFS sheet shear wall) is a code approved lateral force resisting system for light-framed construction in U.S. The shear strength of those shear walls in the design specifications is based on full-scale experiments of specified shear wall configurations. No analytical model or design formulae have been developed for predicting the nominal strength of CFS sheet shear walls. This paper presents a novel analytical model – Effective Strip Model for determining both the nominal strength and the deflection of CFS sheet shear walls subjected to either wind or seismic loads. The proposed design method is applicable to a relative large variety of shear wall configurations and demonstrates good agreements with experimental results. The statistical assessment indicates that the Effective Strip Model is a reliable alternative tool for the engineers to design the CFS sheet shear walls without conducting full-scale tests.
