| 摘 要： | 文献1]在计算受冲切承载力过程中,钢筋的用量未被充分考虑.通过比较冲切承载力的试验值和有限元计算值,确定有限元模拟的可行性,并探讨不同配筋率下的板柱连接冲切的破坏机理.将有限元计算与不同国家规范方法进行了比较,确定文献6]拟合效果较好,并以此为参照,认为用显式来代替我国现行的隐式冲切承载力公式更加合理.

| Abstract: | In the process of calculating punching shear strength with the design code of concrete structure(GB50010-2002),the influence of reinforcement ratio has not been taken into account.This paper ascertains the feasibility of finite element simulation through the comparison of experimental value and analogue value,and discusses the ultimate bearing capacity and failure mechanism in different reinforcement ratios.The conclusion shows that the curve-fitting of BS8110 is far more excellent.Taking BS8110 as a reference,it is preferable to use explicit formula instead of implicit formula used in our country. |
