摘要: 通过对4榀低周反复荷载作用下的不同剪力连接度的端板螺栓连接的组合梁、钢筋混凝土柱节点的试验,得出该类型节点在反复荷载作用下的滞回曲线,并探讨其恢复力特性,并结合试验结果对节点的破坏形态、应变规律、延性、滞回曲线等抗震性能进行分析和讨论。由试验结果可以看出,组合节点的刚度退化随荷载增加而增大。其延性及耗能能力均随剪力连接度的减小而减小。

Abstract: Based on the experiments of 4 specimens of the endplate bolted SC beam and RC column joints under low cyclic loadings, hysteretic curves of the joints are obtained and the characteristics of restoring force are discussed.Uniform formula for calculating the skeleton curve is deduced.In terms of the test results, failure pattern, strain law, ductility, rigidity degeneration and energy dissipation are studied.From the results, it can be concluded that the ductility and the energy dissipation are diminished with the decrease of stud connector.
