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。
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.
