为了对比异形柱框架-剪力墙结构与框架结构在抗震性能、破坏机理等方面的异同,探讨其在高烈度地震区的适用性,根据相同的背景情况设计制作了一个1/8比例的10层异形柱框架-剪力墙模型,进行了振动台试验。根据设计计算的结果和振动台试验中出现的现象及其分析,研究了计算方法的适用性、结构的总体抗震性能和破坏机制。指出该体系具有易于满足位移要求、在大震中以梁铰机制为主、抗倒塌能力强等特点;同时通过与框架结构破坏现象的对比,说明了这种体系可以有效地解决节点承载力问题,在高烈度区应用异形柱结构时应优先采用。
In order to compare the similarities and differences between the special-shaped column-shear wall structure and the frame structure in terms of seismic performance and failure mechanism, and to explore their suitability in high-intensity seismic areas, a 1/8 ratio of 10 Layer special-shaped column frame-shear wall model, a shaking table test. According to the results of the design calculation and the phenomena occurring in the shaking table test and its analysis, the applicability of the calculation method, the overall seismic performance of the structure and the failure mechanism are studied. It is pointed out that this system has the characteristics of easily meeting displacement requirements, mainly using beam hinge mechanism in large earthquakes and strong anti-collapse ability. At the same time, this system is proved to be effective in solving the problem of node bearing capacity by comparing with the failure of frame structure. In the high intensity zone application of special-shaped column structure should be prioritized.
