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精细的三维非线性有限元分析,得出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。
Based on geometry, material and state triple-nonlinearity two specimens of this kind of connection with different bearing capacity are analyzed using finite element method. From finite element analysis the P - △ curves and hysteretic loops of this kind of connection are got. Through the comparison of the performance under forces of this kind of connection to that of the beam-to-column rigid connection without cantilever beam splicing it has been found that this kind of connection with a lower bearing capacity has a good ductility, plastic rotational capacity and energy dissipation capacity.
