【摘要】 针对某楼板开洞的复杂框支剪力墙结构高层商住楼制作了1/20整体试验模型,进行了模型的振动台试验,得到了结构在不同裂度地震作用下的加速度、速度、位移及应力应变曲线,分析了结构的动力特性和动力荷载下的受力特点。研究结果表明,合理的楼板开洞可有效减小转换层以上结构的侧向刚度,避免结构沿竖向产生较大的刚度突变。更多还原

【Abstract】 A 1/20 cement model of a complex frame supported shear wall structure tall building is put to the dynamic test under simulated earthquake load on shaking table.By analyzing the dynamic properties,the earthquake responses and the weak positions of the structure,this paper gives the conclusion that the lateral stiffness above the transfer-story is close to that of stories below the transfer-story because some slabs are removed,which is useful to avoid the lateral stiffness sudden changing along the height of the building.The paper also gives advises to the design of similar structure building.7 tabs,4 figs,6 refs.更多还原
