【摘要】 一种新型复杂结构体系——框支配筋砌块砌体剪力墙结构兼顾了配筋砌块砌体剪力墙结构和框支混凝土剪力墙结构的优点。本文对三榀具有不同侧移刚度比的配筋砌块砌体框支剪力墙结构进行了在水平地震中的破坏形态的研究;研究了这种结构的破坏机理。试验结果表明,框支配筋砌块砌体剪力墙结构的初始弹性侧移刚度比对结构的薄弱层的位置和破坏形态具有重要影响,随着结构侧移刚度比的减小,转换层上部l～2层结构的破坏明显增加。后两榀底部两层框剪框支配筋砌块砌体剪力墙结构的整体工作性能良好,较底部两层框架框支配筋砌块砌体剪力墙具有更好的抗震能力。更多还原

【Abstract】 A new type of complex tall building-FSRMW(frame-supported-reinforced-masonry-shear-wall) combines the advantages of RMW(reinforced-masonry-shear-wall) and FSRCW(frame-supported-reinforced-concrete-shear-wall).Failure modes of three specimens with different lateral stiffness ratio have been analyzed by substructure pseudodynamic testing.The damage mechanisms of test models are investigated.The testing results show that the lateral stiffness ratio of the structure influences on the soft story and the failure mode.The seismic performance of the structure with frame-shear-wall-supported reinforced masonry shear wall is better than that of the structure with frame- supported reinforced masonry shear wall.更多还原
