Non-conventional building: stick-built systems – Methodologies for prediction of shear wall response

In the last years, the applications of cold-formed steel structures in domain of low-rise buildings are increasing. The seismic behaviour of these structures is influenced by the lateral response of shear walls, which are usually sheathed with panels. Different approaches are available to evaluate the lateral response of sheathed cold-formed steel (SCFS) walls: tabulated, numerical and analytical methodologies. In literature, a large number of methods developed for the analysis of sheathed wood shear walls is available and their application is also reasonable in the case of steel-framed shear walls. This paper aims to show the methodologies for prediction of SCFS shear wall response. The application of presented methodologies is illustrated using a calculation example by showing the results in terms of resistance and stiffness for SCFS shear wall.
