Abstract:
Based on the orthotropic elastic thin plate theory, the mechanical performance of shear wall subjected to non-planar bending moment acting from the beam was studied. The analytical solutions for rotational stiffness of the joint and effective width of the wall were obtained. An equivalent frame model was introduced. The out-of-plane rotational stiffness of the joint can be derived by assuming that an effective width of wall near the joint was acted as an equivalent column. The theoretical results were compared with the finite element results obtained by ANSYS and good agreements were found. Based on practical engineering situation, the results of calculation show that the rotational stiffness of the non-planar beam-wall joint is not small enough to be neglected.
