ABSTRACT
In the last years, the seismic performance of cold formed steel (CFS) systems has been object of study by a large number of research teams. The main parameters influencing the system behaviour under horizontal loads have been defined and the possible mechanisms of collapse have been identified. Therefore, at the moment, the development of upgraded specifications and design tools that could be readily used by designer is a must. For these reasons, this paper aims to propose a seismic design procedure that allows the shear wall components to be defined in few steps. The procedure is based on the recognized assumption that the best performance of a CFS shear wall is achieved when the sheathing-to-stud fasteners failure is reached. Moreover, it accounts the results of previous studies that defined the relation between behaviour of shear wall and fastener spacing. Hence, by defining three nomographs, the proposed procedure allows the sheathing-to-stud fasteners and all the other shear wall components to be defined. The latter are determined in accordance with capacity design criteria. Finally, the applicability of the presented procedure is verified through a case study.
