ANALYTICAL MODEL FOR SHEAR SLIP OF CRACKED CONCRETE

The formulation of basic consitutive equations and modeling of the four coefficients which relate the stresses and displacements at a crack are descibed. They reflect such typical characteristics as shear transfer due to aggregate interlock, cross effect (crack dilatancy and dilatancy and frctional contact slip) and path dependence. Numerical examinations demonstrate that the shear stress versus shear displacement relationship exhibits highly nonlinear behavior and is quite sensitive to extensional stiffness of reinforcing bars crossing a crack. Numerical comparisons indicate satisfactory agreement with the available test data. An advantage of the model is that the derived stiffness matrix of cracked concrete can readily be incorporated into existing finite element codes by modifying the constitutive matrix to be symmetric, requiring especially when large-scale reinforced concrete structures like nuclear facilities are dealt with.
