混凝土板冲切锥体形状研究

Discussion on the Shape of Punching-shear Cone of Concrete Slabs

分析了混凝土无冲切筋板冲切承载力及冲切计算周长u_m的取值,为解决同一荷载值不同荷载作用面的冲切承载力的计算中出现的问题,提出一种u_m的取值方法。

In this paper, the punching shear capacity of concrete slabs is analyzed and the punching shear circumference(um) is defined . And a method for calculating um is presented to re-solve the defect in calculating punching-shear strength under the same load on different loading area .
