摘要
本文旨在研究柱端与楼板之间不同连接方式对于结构抗震性能的影响。通过常见的不同连接方式共设计出六个模型:固定框架、下端铰接框架、上端铰接框架、下端滑动框架、上端滑动框架、摇摆框架。通过小型振动台试验输入不同地震波类型及幅值,对比分析各个模型下结构的响应。对比分析表明,放松框架柱的约束可以降低结构的基频,并有效减小结构的加速度响应;不同连接方式的结构的响应受地震波类型的影响显著。
This paper aims to study the influence of different connection methods between column ends and floor slabs on the seismic performance of the structure. Six different models are designed through common connection methods: fixed frame, lower hinged frame, upper hinged frame, and lower sliding frame, upper sliding frame and swing frame. This paper inputs different seismic wave types and amplitudes through a small shake table test, compares and analyzes the structure response under each model. Comparative analysis shows that relaxing the constraints of the frame columns can reduce the fundamental frequency of the structure and effectively reduce the acceleration response of the structure. The response of structures with different connection methods is significantly affected by the type of seismic wave.
