摘　　要：基于附加角钢预应力装配框架中节点抗震性能试验研究,运用ABAQUS软件对其进行数值模拟,并深入分析了不同因素对节点骨架曲线及极限荷载的影响。结果表明:有限元分析结果与试验结果吻合性较好,验证了本文所采用的有限元分析手段是可靠的;增加轴压比、有效预应力、混凝土强度等级在一定范围内可增强节点的承载能力,而梁普通纵向钢筋配筋率的增大对节点承载力影响不大。该研究可为附加角钢预应力装配式框架结构抗震设计提供参考。Based on the experimental study on seismic behavior of joints in additional angle steel prestressed assembly frames, this paper uses ABAQUS software to numerically simulate and analyze the influence of different factors on the skeleton curve and ultimate load. The results show that the finite element analysis results are in good agreement with the experimental results, which proves that the finite element analysis method used in this paper is reliable;increasing the axial compression ratio, effective prestress, and concrete strength grade can enhance the bearing capacity of the node within a certain range. Capacity and the increase of the normal longitudinal reinforcement ratio of the beam have little effect on the bearing capacity of the joint. This study can provide a reference for seismic design of prestressed fabricated frame structures with additional angle steel.
