提出了一种装配式梁柱节点新形式,带悬臂梁段的框架柱与框架梁进行拼接,通过L形角钢进行节点加强,形成全螺栓装配式节点.为研究该节点的力学性能,以前期试验作为研究基础,对带悬臂梁段拼接的装配式新型梁柱节点采用ABAQUS软件进行参数分析.首先建立装配式梁柱节点的足尺试验模型,与试验结果进行对比验证;然后,对带悬臂梁段拼接节点进行参数化分析并且考虑加劲肋数量、横板厚度、耳板厚度、L形角钢长度和翼缘螺栓数量的因素,得到不同参数下节点的力学性能.
A new form of assembled beam-column joint is proposed,and in order to study the mechanical properties of this joint,the parametric analysis of the assembled new beam-column joint with cantilever beam segment splicing is carried out by ABAQUS software on the basis of the preliminary experimental re-search.First,the test model of the assembled beam-column joint was established by ABAQUS,and the test results were compared and verified.Then,the parametric analysis of the spliced joint with cantilevered beam segments was carried out and the mechanical properties of the joint under different parameters were obtained by considering the number of stiffening ribs,thickness of cross-plate,thickness of plates,and length of L-shaped angle steel.
