摘　　要：总结了国内外关于钢筋混凝土及预应力混凝土板柱节点拟静力试验的研究成果,采用最小二乘法分析了板柱节点层间位移比与重剪比之间的相关关系,分别给出了钢筋混凝土及预应力混凝土板柱节点不配置抗冲切钢筋时,具有95%保证率的的层间位移角与重剪比关系曲线,提出了与1/100及1/50层间位移角对应的、可不作抗震弹塑性变形验算的重剪比限值。In this paper, domestic and foreign research resuhs about the pseudo-static test of reinforced and prestressed concrete slab-column connections are presented, the relationships between the interstory drift ratio and the ratio of punching shear to nominal shear strength of critical section according to GB50011-2001 with the least square method are analyzed, the correlative curves with 95 % guaranteed rate of the interstory drift ratio and the ratio of punching shear to nominal shear strength of punching critical section （ Vg/Vu ） are obtained, and the upper limits of Vg/Vu correspond to 1/50 and 1/100 inter-story drift ratio for those checking calculation of seismic elastic-plastic deformation can be omitted of reinforced and prestressed concrete slab-column connections without punching reinforcement are recommended respectively.
