An analytical method for reinforced concrete plates subjected to biaxial bending moments was prposed in this study. This method divides an original plate into two discrete layers of tension and compression zones. These layers are treated as reinforced concrete plates subjected to membrane force.
In the analysis of the tensile layer, tension stiffening of concrete and shear transfer along the surface of cracks were incorporated. Considering the effect of two-way cracks, the capacity of interface shear transfer was reduced according to the ratio of principal moments.
Moreover, the apparatus for experiments of biaxial bending was newly developed to obtain the accurate test data.
The agreement between analytical results and experimental ones was fairly well and the proposed analytical method was found to be useful to estimate the behavior of reinforced concrete plates subjected to biaxial bending moments.
