摘要
通过9根留有施工缝柱和整浇柱的伪静力试验，研究了轴压比、施工缝接缝面处理方法对柱抗震性能的影响，对构件的破坏特征、承载能力、滞回曲线、骨架曲线以及刚度退化特性进行了对比分析．试验结果表明，在轴压比较低的情况下，有施工缝柱的承载能力会降低3％～7％，位移延性系数降低最大可达30％；在较高的轴压比下，施工缝对构件的抗震性能影响并不显著．最后，从施工方法、受力性能、界面处理等方面，对有施工缝柱抗震性能低于整浇柱的原因进行了理论分析．
Based on the pseudo-static test of 9 frame columns with construction joint and monolithic cast columns, the influences of the axial compression ratio and the treatment methods of construction joint hyste on the seismic behavior of columns are studied. Failure characteristics, bearing capacity, retic curves, skeleton curves and stiffness degradations of members are analyzed and compared. ratio, the effect of construction joints for earthquake resistant behavior of columns is indistinctive. Finally, the earthquake resistant behavior of columns with construction joint lower than monolithic cast columns is analyzed from 3 aspects of construction method, stress behavior and interfacial treatment.
