Elastic Analysis of Beam-Wall Joints Subjected to Out-of-Plane Bending

The mechanical performance of reinforced concrete beam-thin-wall joints under out-of-plane bending moments is studied and the analytical solutions in terms of stresses and rotational stiffness of the wall are obtained. For convenience, the equivalent bending width of the shear walls is introduced and obtained based on two equivalence principles. A detailed parametric study of the equivalent bending width is carried out, including geometric parameters, boundary conditions, and reinforcement ratio of the beam-wall joint in shear wall. Some simplified formulae for the equivalent width are proposed and compared with both the analytical solutions and the experimental results. Good agreements are found.
