| Abstract: | A set of programs for solving elastic-plastic seismic response of multistory masonry buildings was written by Matlab,which combined Newmark time-history method with two-linear model of stiffness degradation.A four-story masonry building was taken as the analyzed object,and the actual and artificial-simulated blasting seismic waves were used as the input loads,whose characteristic parameters were transformed based on a certain principle.According to calculated results of amplitude for all structural elastic-... |
