螺栓连接方钢管混凝土柱-钢梁组合框架结构拟静力有限元分析

Jianzhu Gangjiegou Jinzhan
本文应用ABAQUS软件建立了1层1跨螺栓连接方钢管混凝土柱-钢梁组合框架结构的三维精细有限元模型来进行拟静力分析，螺杆、螺母等细小构件都采用实体建模。模型充分考虑了钢管对核心混凝土的约束作用、螺杆与螺母的预紧力作用以及螺栓与T形件、钢管、钢梁的摩擦接触作用，模型分析的破坏形态、荷载-位移滞回曲线、刚度退化-位移曲线等计算结果与已有拟静力试验结果符合较好。在此基础上，进一步分析了组合框架结构的螺栓滑移情况、柱轴压比、钢管横向变形系数、核心混凝土应力-应变曲线、结构损伤、塑性耗能分配机制。结果表明 ...
