摘要:
通过带侧板抗弯钢节点低周反复加载试验,阐述了其破坏过程和破坏机理,得到了节点滞回曲线和极限承载力; 利用有限元分析软件ANSYS对试验进行了模拟,计算结果与试验吻合良好; 讨论了梁、柱的截面尺寸和侧板厚度对钢节点性能的影响。结果表明:节点具有良好的耗能能力和延性,并使塑性铰发生在梁上; 增大梁截面尺寸可以最有效地增大节点的初始刚度、屈服荷载和极限荷载; 柱截面尺寸对节点的初始刚度影响较明显,但对极限荷载和屈服荷载的影响很小; 侧板厚度对节点力学性能影响很小。
Abstract:
Low-cyclic loading tests conducted on side plate moment connection were presented, including the test phenomena and failure mechanism, the hysteretic performance and ultimate bearing capacity. Finite element analysis software ANSYS was adopted to establish models of the tests and the results were almost identical to the tests. ANSYS was also adopted to analyze effects of beam and column sizes and thickness of side plate. The results show that the connections have a good capacity of energy dissipation and cause the ductility of structure with formation of plastic hinges in the beams. The initial stiffness, yielding load and ultimate load increase obviously with the increase of the size of beam. The size of column has remarkable influence on initial stiffness. But it has negligible effect on yielding load and ultimate load. The thickness of side plate has negligible effect on the behavior of the connection.
