摘要
进行了6个核心型钢混凝土柱试件的低周反复加载试验,研究了核心型钢在转换层的截断形式和核心型钢在底梁的锚固方式、沿核心型钢弱轴加载等构造措施对核心型钢混凝土柱抗震性能的影响。通过试验研究检验了不同构造措施对试件的破坏形态、强度、变形能力和滞回特性等抗震指标的影响。研究结果表明:本文采用的核心型钢柱中截断的构造措施合理,核心型钢通过底部端板和预埋螺栓与底梁连接的锚固形式基本可靠,沿核心型钢弱轴方向加载对核心型钢混凝土柱的抗震性能影响不明显。以上研究成果可以为工程实践提供参考。
Six core steel reinforced concrete（CSRC） columns are tested under cyclic loading to investigate the influence of truncation details of core steel in the transfer story,embedded ways of core steel in column base and loading directions along strong or weak axis of core steel to the seismic performance of CSRC columns.Emphasis is directed on the influence of different seismic design details of CSRC columns to the failure modes,strength,deformation capacity and hysteretic characteristics of specimens.It is indicated that the truncation details of core steel in transfer story are rational and reliable.The embedded ways of core steel in column base through precast steel bolts and steel plate proposed in this paper are basically reliable.No distinct difference is observed between CSRC columns loading along strong or weak axis of core steel.The results of this paper can be referenced for engineering practice.
