摘要
基于带水平短缝低剪力墙的反复荷载的试验研究结果及分析,作者把这一抗震控制设想进一步推广应用于多层带边框剪力墙结构体系,以改善这类结构体系的抗震性能.为了真实地了解地震动荷载作用下开水平短缝多层剪力墙性能,并和相同情况下的普通多层剪力墙的性能相比较,作者按照相似比例关系,制作了两片4层钢筋混凝土小结构模型,进行了直接输入地震波的结构地震模拟振动台试验。试验经历了结构弹性、开裂直至破坏全过程,研究了结构在各个阶段的动力特性变化及动力反应,并比较了两片小结构模型的破坏形态。试验结果表明,带水平短缝剪力墙结构的抗震性能明显优于普通剪力墙结构。
The structural control idea based on the experimental results
of lowrise shearwall with horizontal short keyways subjected to cyclic loading and its analysis is applied to multi-story framed shearwall structural
system so as to improve earthquake resistant behavior of structures concerned. In order to understand real behavior of multi-story shearwall with horizontal keyways in action of seismic loads and to make the comparison
with that of ordinary shearwall at the same time, the author constructed
2 small R. C. structural models with 4-story high, The shaking table test of the models by directly inputing seismic waves was carried out, the test procedure went through elastic, cracking and failure stage of structures.
Dynamic characteristic and dynamic response of structures at different
stages was stuided, and comparison about failure pattern of 2 models was also made. The test results showed that earthquake resistant behavior of shearwall with horizontal keyways is obviously better than that of ordinary
shearwall.
