Abstract

The aim of the paper is to assess the usability of nonlinear simplified methods for practical application for regular frame structure with different stories. Estimation of target displacement is performed using CSM, ELM, CM and DDM. All applied procedures are based on pushover analysis and response spectrum method. The pushover analysis is used to develop pushover curve, which is idealized to determine the characteristics of SDOF system. For regular frame structure simplified methods yield to results of adequate accuracy. For all the applied distribution of lateral loads were obtained almost identical levels of strength capacity, stiffness and ductility.
