摘　　要：进行了3个剪跨比等于3.0的钢筋混凝土连梁模型的伪静力试验,结合前一批试验[1]的部分试验结果,考察了提高配箍参数、降低纵筋配筋率和增加核心钢骨对改善连梁抗震性能的效果。通过与其他学者的试验结果进行比较和分析,建立了连梁破坏位移角的回归计算公式。Based on the test results of three reinforced concrete coupling beams with moderate shear span of 3.0, and referring to the test data of the first batch of tests conducted by the authors, the effect of lateral reinforcement, longitudinal reinforcement and steel tube on seismic performance of reinforced concrete coupling beams in HongKong is examined. Combining the test results of this paper and those of other researchers, a regression formula is proposed for ultimate drift ratio of reinforced concrete coupling beams.
