In frame-shear wall and frame-core tube structures, there are at least two different kinds of connecting joints between the reinforcement concrete floor beam and the shear wall or core tube. One is coplanar joint at which the beams are coplanar with the walls;the other is non-planar joint at which the beams are at arbitrary angles to the walls. The focus of the present study is the latter which is the right angle beam-wall joints. So far only a few investigations concern the non-planar beam-wall joint.a nonlinear FEA is carried out for the shear-walls with hidden columns based on ANSYS. The effects of the different width of the hidden column on the non-planar load-carrying capacity of shear-wall are taken into account and the numerical results are proved correctly by comparing with the experimental results.
