摘要
梁柱拼接节点是装配式钢结构的关键连接部位,连接梁柱等构件并将力有效传递到各构件,是一个交汇点,受力比较复杂,且影响节点强度、刚度的因素比较多.本文利用大型通用非线性有限元分析软件ABAQUS对每层带斜撑和无斜撑的边节点和中间节点四种节点进行数值模拟,采用弹塑性有限单元法,分析节点的强度和节点角度,根据弯矩与转角的关系判断节点为刚性还是非刚性.分析结果表明该节点为刚性节点.
Beam stitching node is the key of prefabricated steel structure connection parts, Connecting beams, and other artifacts and force transfer to each component; It is an intersection, Stress is more complex, and factors influ- encing the strength and rigidity of the node is more, so using general nonlinear finite element analysis software ABAQUS to each layer with brace and brace four node and the edge of the middle node are numerically simulated, by elastic - plastic finite element method, the strength of the analysis of node and the node point, according to the relation ship of bending moment and comer for rigid or non - rigid judgment node. Software simulation analysis resuits for the node is rigid nodes.
