【摘要】 近年来地震灾害频发,居民住宅的抗震性能越来越得到重视.通过对灾区房屋安全性评估和震损情况调查发现大量框架结构建筑的倒塌有共同的现象:框架柱柱顶施工缝位置破坏更为突出.实际施工中有很多施工单位不严格按照规范规定的施工缝处理方法施工,由此对框架柱抗震性能的影响需要试验研究.本文介绍了9根试件进行低周反复试验,分析试验现象和实验数据得到试件的滞回曲线、位移延性系数、粘滞阻尼系数等抗震性能指标.试验结果表明:在中低轴压比下,应该对框架柱留置的施工缝按规范进行严格处理;在高轴压比下,可以不对施工缝进行严格处理.更多还原

【Abstract】 In recent years,earthquake disasters Frequently occurred,earthquake resistant capability of residential buildings have been paid more and more attention.Through the Post-seismic Damage Assessment of thebuildings in disaster area,we found that a large number of collapse of frame structure buildings have common phenomenon that the damage of construction joints of frame column capitals is more prominent.In the actual construction many construction units do construct unstrictly according to the construction standard of treatment method of construction joint,the influence of the way to the frame column of seismic performance need experimental study.This paper introducts the test of 9 test columns under low cyclic static loading,analysis the experimental phenomena and experimental data,and gain specimens of seismic performance index,such as hysteresis curve,displacement ductility,viscous damping coefficient.the test result show that in the middle and low axial compression ratio should construct strictly according to the construction standard of treatment method of construction joint,and in the high axial compression ratio could construct unstrictly.更多还原
