| 摘 要： | 为研究外包钢-混凝土组合梁与钢管混凝土柱连接节点的抗震性能,基于外包钢-混凝土组合梁与钢管混凝土柱连接节点低周反复荷载作用下的试验结果和有限元的模拟,分析了两类试验节点的滞回特性,提出外包钢-混凝土组合梁与钢管混凝土柱连接节点的三折线恢复力模型及其特征参数的取值范围,并给出恢复力模型表达式。结果表明,试件具有良好的耗能能力,建立的恢复力模型骨架曲线与试验值接近;有限元与试验所得的滞回曲线及骨架曲线在弹性阶段吻合较好,随着荷载的反复,两者之间的差异逐渐增大。

| Abstract: | In order to study the seismic performance of the steel-concrete composite beam to concrete-filled steel tubular column joints,this paper analyzed the hysteretic capacity of two experimental joints based on the experimental results and the simulation of the both joints under low cyclic loads.The author proposed the tri-linear restoring force model and the range of the feature component,and also the expression of the restoring force model.The result shows that the specimens have good seismic performance and the skeleton curve of the established restoring force model is similar to the experimental values.The skeleton curves and the hysteretic curves of the experiment and the FEA match well during the elastic stage.But the differences of them increase under the cyclic load. |
