摘要
提出一种应用于矩形钢管柱-H形梁连接的模块化节点型式,对模块化节点型式和传统焊接节点型式进行了单调加载的非线性有限元模拟,对不同节点型式发生延性断裂的倾向大小作出评价。分析研究表明,提出的模块化节点型式比传统的焊接节点型式延性好,能更大程度地利用节点域剪切塑性变形的稳定耗能能力。
A modular node for a rectangular steel tubular column to an H-beam is proposed. Nonlinear finite element analysis is conducted to stimulate the monotonic loading of a modular node and a traditional welded node. The propensity for the ductile fracture initiation of different nodes is evaluated. The research shows that the proposed modular node exhibits better ductility, leading to a larger extent to utilize stable energy dissipation capacity from the shear plastic deformation of a panel zone.
