Study of the hysteretic capacity of new steel-concrete composite beam to concrete-filled steel tubular column joints

为研究新型组合梁与钢管混凝土柱连接节点的抗震性能,开展了新型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研究,对这种类型节点的滞回性能进行了研究,在实验研究的基础上,提出了新型组合梁与钢管混凝土柱连接节点的三折线恢复力模型,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。

In order to study the seismic performance of the steel-concrete composite beam to concrete-filled steel tubular column joints, this pa- per analyzed hysteretic characteristic by low cyclic loading on the new type of composite beam to concrete-filled steel tubular column joints. The author proposed the tri-linear restoring force model based on the experimental results. The result shows that the specimens have good energy dis- sipation, and the skeleton curve of the restoring force model is similar to the experimental values.
