摘要
对装配式临时看台节点的抗弯、抗拉和抗压承载力进行了多组试验,研究探讨节点的力学性能,得到了其极限承载力、破坏模式及荷载-位移曲线,在此基础上给出了节点的简化计算模型,并通过对整体格构柱的有限元和加载试验分析,验证了节点简化模型的正确性。
A series of tests on the bending,compressive,tensile capacity of the nodes of temporary assembly grandstand were carried out.The mechanical properties were discussed.Its ultimate bearing capacity,failure mode and load displacement curves of the nodes were obtained.On this basis,a simplified calculation model of the node was given.By comparing finite element analysis with load tests on trellis columns,the accuracy of the simplified model of the node was verified.
