摘　　要：对一组留置施工缝,一组未留置施工缝的两组单榀两层两跨框架结构进行了低周反复荷载作用下的试验研究,对两组框架的滞回性能、延性、刚度退化等性能作了深入的分析。研究了框架结构中因为施工缝的存在而对结构整体抗震性能的影响。试验研究结果表明:施工缝的存在对结构抗震性能的影响还是比较明显的。It is designed a contrast experiment on two sets of two-span and two-story RC frames under low cycle reversed loading, One frame has construction joints while the other has not. According to the experiment results, hysteresis behavior, ductility, rigidity degeneration etc. are studied systematically. And studies show that the RC frame without construction joints has better seismic performance than the other.

关 键 词：施工缝 抗震性能 低周反复 滞回曲线
