| 摘 要： | 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。

| Abstract: | Based on preceding shaking table test on a six-story reinforced concrete(RC) frame with specially shaped columns,a ten-story RC shear-wall frame with specially shaped columns under same conditions is designed for 1/8 scale shaking table test.The test focuses on the differences in seismic performance and damage mechanism between shear-wall frame and frame with specially shaped columns,and suitability for high intensity zones.Based on numerical results of structural design,experimental observation and analysis,the applicability of computational model,global seismic performance and damage mechanism of structure are revealed.Experiment also shows advantages of the structure,that is easy attainment for drift control requirement,predomination of beam hinge mechanism under major shock,and good collapse-proof capacity.The comparison of damage phenomena with frame shows that the shear-wall frame is an effective solution for requirement on joint capacity and is favorable structural system for the application of specially shaped column structures in high intensity zones. |
