【Abstract】 By resorting to the series-parallel model,a non-linear dynamic time history analysis was carried out to investigate the earthquake resistant performance of the upside-soft multi-story masonry strutures.Several parameters that have significant effects on the seismic responses were studied,such as the story number of the structure,the stiffness ratio of the side wall to the intermediate column,and the spacing interval of cross walls,and some traits of this kind of buildings were discussed.更多还原
