摘要:
以某大型型钢混凝土结构主厂房为原型,采用 ABAQUS 混凝土塑性损伤本构模型,研究配置不同方向的短肢墙对 SRC 异型边节点抗震性能的影响程度.数值分析表明:配置纵向短肢墙可以改善该类异型边节点延性与破坏机制,避免“柱铰型”破坏机制出现;配置横向短肢墙可以大幅度提高该类异型边节点承载力与刚度,并有效地降低了刚度退化率;配置双向短肢墙可以明显地增大该类异型边节点滞回面积,改善抗震性能.
Abstract:
The paper presents the studies on different seismic behavior of steel reinforced concrete (SRC) abnormal exterior joint with short-limb wall at different directions, by concrete damaged plasticity model of ABAQUS, based on the steel reinforced concrete frame main power house. Numerical analysis indicates that the short-limb wall at longitudinal direction can improve the ductility and failure mechanism of the joint, avoiding the failure mechanism at column hinge. The short-limb wall at transverse direction can increase capacity and stiffness of the joint substantially, and decrease the degradation rate of stiffness. The short-limb wall can enlarge the area of hysteretic hoop and improve seismic behavior of the joint.
