【摘要】 以某框架—剪力墙工程实例为背景,运用PUSH&EPDA软件对其进行了静力弹塑性分析,主要探讨了结构随着荷载逐步加大过程中等效阻尼比的变化情况,在此基础上取不同的阻尼比对结构进行动力弹塑性分析,通过层间位移角的对比,探讨了弹塑性分析中结构阻尼比的取值问题,为阻尼比的取值提供了参考依据。更多还原

【Abstract】 Taking a frame-shear wall engineering example as the background,using PUSH&EPDA software made static elastic-plastic analysis on it,mainly discussed the variation situation of equivalent damping ratio of structure with the load of increasing gradually process,based on this taking different damping ratio made dynamic elastic-plastic analysis to structures,through the comparing to layer displacement angle,discussed the value problem of elastic-plastic analysis on structural damping ratio,provided reference basis for the value of damping ratio.更多还原
