钢筋混凝土异形柱框架-短肢剪力墙结构振动台试验研究
|
摘要
异形柱框架-短肢剪力墙结构是介于异形柱框架和异形柱框架-剪力墙结构之间的一种新型结构体系。本文通过对一幢12层钢筋混凝土异形柱框架-短肢剪力墙结构1/7比例模型的地震模拟振动台试验,系统研究了该结构体系的动力特性、地震反应及破坏机理等。试验结果表明,该结构体系属于梁铰破坏机制,能满足延性设计要求,且具有良好的抗震性能和较强的抗震能力,达到了抗震设防标准。因此,该结构体系较适用于小高层住宅结构设计。
Reinforced concrete frame of short-pier shear wall structure system with special-shaped columns is a new structure variety of frame structure and frame-shearwall structure.The dynamic characteristics,response and destroyed form of this new style structure system,reinforcement of concrete frame of short-pier shear wall structure with special-shaped columns,were studied in this paper,by means of shaking table test of a 12-story model.The results showed that this structure system behaved as beam hinge in collapse,and it owned good aseismic performance and strong capacity for defending against rarely earthquake,so that it can satisfy the requirement for earthquake resistance.So this structure system can be suitably used in mid-highrise residence.
