Abstract

The lateral behavior of cold-formed steel shear wall is dependent on several factors including the type of sheathing used. However, only a limited number of sheathing types have been studied using specific installation method. In this study, due to the high demands of builders to use local materials for sheathing light steel frames, which, in addition to being abundant and easy to obtain, can also create a variety of designs such as stone or brick to match the facade of existent parts of the building, two full-scale samples of cold-formed steel shear walls in dimensions of 1.2×2.4 meters sheathed by porcelain ceramic with different configurations have tested under combined constant gravity loading and standard cyclic lateral loading regime. After calculation of ductility and response factors by using of specimens tests results, The seismic effect of the sheathing rectangular pieces orient, which can be installed in either horizontal or vertical strips, is investigated. The results of the tests show that porcelain sheathing pieces installation in vertical strips instead of horizontal strips causes a decrease of approximately 50% in Energy Dissipation and 18% in ultimate lateral resistance without effect on seismic response modification factor, R.
