摘要:在考虑几何、材料、状态三重非线性的基础上,对此类节点钢梁拼接节点承载力不同的两个试件进行了精细的三维非线性有限元分析,得出了此类节点在单向荷载作用下的P-Δ曲线和在循环荷载下的滞回曲线,并将此类节点的性能与无拼接节点的刚性梁柱连接的性能进行了对比。结果表明,拼接节点承载力较低的此类节点有良好的延性、塑性转动能力和耗能能力。

Abstract: Based on geometry, material and state triple-nonlinear two specimens of this kind of connection are analyzed using finite element method; the beam-to-beam splicing connection bearing capacity is different of these two specimens. From finite element analysis get the P-Δcurves and hysteretic loops of this kind of connection. Through compared the performance under forces of this kind of connection and no cantilever beam splicing beam-to-column rigid connection, found that this kind of connection which the bearing capacity of beam-to-beam splicing connection is lower, have a good ductility, plastic rotational capacity and energy dissipation capacity.
Keywords: beam-to-column connection with cantilever beam bolted-splicing; high-strength; plastic hinge;
