The tensile cracking of concrete is a major factor contributing to the nonlinear behavior of reinforced concrete elements. This motivated the writers to develop analytical models for the tension stiffening effect.
This paper deals with mechanical behavior of isotropic/nonisotropic reinforced concrete panels subjected to in-plane shear, and its characteristics are examined by numerical calculations as well as by comparisons with experimental results. Nonlinear shear deformation, rotation of principal angles of concrete stress and total strain, influence of bond stiffness, and crack widths and slip are especially discussed.
