摘　　要：基于新型装配式节点(PPEFF节点)拟静力试验,用有限元软件ABAQUS对PPEFF节点进行有限元非线性分析。得到的滞回曲线与试验滞回曲线吻合良好,说明该有限元模型能够较好地模拟节点的受力状态。在此基础上,研究混凝土强度等级、轴压比、箍筋配箍率等相关参数对PPEFF节点抗震性能的影响。结果表明:混凝土强度等级对节点承载力的影响较为明显,轴压比对节点承载力的影响较小,而箍筋配箍率对节点承载力影响不明显。Based on the quasi static test of a new type of fabricated joint(PPEFF joint),the finite element nonlinear analysis of PPEFF joint is carried out by using the finite element software ABAQUS.The obtained hysteretic curve is in good agreement with the experimental hysteretic curve,which shows that the finite element model can better simulate the stress state of the joint.On this basis,the effects of concrete strength grade,axial compression ratio and stirrup ratio on the seismic performance of PPEFF joints are studied.The results show that the influence of concrete strength grade on the joint bearing capacity is obvious,the influence of axial compression ratio on the joint bearing capacity is small,and the influence of stirrup ratio on the joint bearing capacity is not obvious.
