A simplified non-linear procedure for buildings with shear walls

A simple and easily applicable analytical method is proposed to obtain the capacity curve of buildings with shear walls as the first stage of a seismic pushover analysis. The method is based on controlling the curvature distribution of shear walls. Accuracy of the method was examined based on data of three sample buildings compiled from the literature. The buildings have different floor areas, number of storeys and cross-sectional areas of shear walls. The method can be economically used with respect to both the computation time and the required equipment. The findings of this paper should be helpful for practising engineers as a quick and dependable hand calculation method for assessing the earthquake resilience of buildings.
