摘要
为了检验刚性钢框架梁柱连接的抗震性能,对六个大尺寸的连接试件进行了循环加载试验,试验过程中在柱端施加了轴向压力。试验中,刚性连接试件在循环荷载作用下没有表现出足够的延性。试验结果表明:全焊梁柱连接的滞回性能好于栓焊连接;较弱节点板的梁柱连接能产生较大的塑性变形;翼缘对接焊缝的质量对梁柱刚性连接的滞回性能有很大影响。根据试验结果提出了设计施工建议。
In order to investigate the seismic behavior of the steel beam- to- column moment, cyclic- loading tests were conducted on six large- scale welded flange- bolted web and full welded steel beam- to- column moment connections, a constant axial force was applied at the end of the column during the test. Results of the experiment showed that such connections didn't have enough ductility, the results also showed that the ductility of the full weld connections were better than the welded flange- bolted web ones, and connections with weaker panel zone could develop larger plastic deformation. Weld quality appears to have crucial influence on the response of the specimens. Finally, suggestion on design and fabrication based on the results of experiment are presented.
