摘　　要：本文采用有限元软件MSC.Marc研究了低周期反复荷载作用下预制预应力混凝土框架节点的抗震性能,并将其分析结果与试验结果进行对比。结果表明:通过比较混凝土开裂情况、试件变形、钢绞线受力、滞回曲线、骨架曲线,MSC.Marc数值模拟结果与试验结果符合较好。验证了使用该种方法模拟节点受力特性具备可行性、可靠性。This paper applies the finite element software,MSC.Marc,to study the seismic behavior of precast prestressedfabricated concrete frame connections subjected to low cyclic and reciprocal loading,and the finite element analysis results are compared with theexperimental results.The comparison shows that the numerical simulation results of MSC.Marc,e.g.concrete cracking,specimen deformation,steel strand stress,hysteresis curve and skeleton curve,are in good agreement with the experimental results.It is also proven feasible and reliable to simulate the mechanical characteristics of the connections by using this method.
