this area is very necessary.In recent decades,with the development of concrete strength theory,the study[1-5]on the punching shear failure mechanism of slabs is also further deepened.For example,Nielson[6], Juhong Han[7-9]and etc,modifying Mohr-Coulomb theory to study the problem of the punching shear failure,obtained the shape of punching failure surface and the upper limit value of punching failure load.By adopting the twin shear stress theory with two parameters,Zongda Yan [10]gained the calculation method of axisymmetric punching failure load.Anbao Wang, Xiumin Yang[11]and etc,applied twin shear criterion with three parameters on analysis of the punching strength,gaining the upper limit value of axial symmetry punching failure load.The unified strength theory,a new serialized theory that proposed by Maohong Yu[12,13],not only establishes the relationship of various failure criteria,but also produces a series of new standards.It has been flexible applied for different engineering materials
(1.2) Whereβ is the material parameter,and C is the another material parameter,and the ratio of tensile strength to compressive strength for material,α,given by (2) (3) Where b,varying from 0 to 1,is the influence coefficient of intermediate principal stress,and also a parameter for selecting different strength criterion.When a value of n is taken equal to 0,the unified strength theory is a linear criteria.Otherwise,the unified strength theory is the nonlinear criteria.
