| Abstract: | Performance based seismic design of buildings is becoming a trend.Pushover analysis and nonlinear time-history analysis are main approaches in performance based seismic design.On the basis of previous researches and in order to enhance accuracy of pushover analysis and search for softening sections in the structure,the Newton-Raphson iteration and arc-length method have been used to solve nonlinear equations.In particular,pushover analysis of tall structures has been studied in considerable detail. |
