摘　　要：为了考虑在钢筋混凝土框架结构中施工缝的存在对抗震性能的影响,按照抗震设计规范合理设计了两个单榀两层两跨框架结构,一个是完全按照正常施工方法留置施工缝的框架,另一个框架则1一次性浇筑完毕未留置施工缝。通过对两个框架在低周反复荷载作用下的试验比较,对两个框架的破坏形态、滞回性能、位移延性、刚度退化、牯滞阻尼系数等性能进行深入对比分析,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。Two reinforced concrete frames are designed under seismic rules for considering construction joints which one is constructed with construction joints in normal construction way and another is constructed without construction joints. Based on the comparing of two frame in low reversed cyclic loading experiment, failure pattem,hysteretic behavior, rigidity degeneration, energy dissipation etc. are studied deeply,and seismic behavior of frames is also studied while considering construction joints.
