摘要
为评估在地震等强冲击载荷作用下工业货架横梁与立柱挂齿式连接梁柱节点的性能退化情况,基于低周反复加载试验,建立钢结构货架梁柱节点恢复力仿真模型,以滞回耗能能力和延性系数为指标,对梁柱节点的退化性能进行数值分析。结果表明,连接形式对节点的抗震性能影响最为明显,其次是挂片焊接位置、厚度和安装间隙。
To evaluate the performance degradation of hanging-tooth connection beam-column joints between the cross beam and column of the industrial rack under strong impact load such as earthquake,the restoring force simulation model of steel rack beam-column joints is established based on the low cycle reversed loading test.The hysteretic energy dissipation capacity and ductility coefficient are taken as indexes,and then the degradation behavior of beam-column joints is numerically analyzed.The results show that the connection type has the most obvious influence on the seismic performance of the joint,and the second one is the hanging piece welding position,thickness and installation clearance.
