Due to the plastic deformation of the concrete, when the torsion effect is aggravated of the short-leg shear wall joints, the results of the short-leg shear wall joints are quite different from the results worked out by elasticity theory. Therefore, by using ANSYS finite element calculation software, a simulation test can be done of the T-shaped short-limb shear wall joints under the horizontal low cyclic loading. Based on an analysis of its structural deformation, crack and concrete stress, a study has been carried out of the torsional behaviors of the joints. The research results show that the horizontal force exerted on the beam ends can cause torsional failure to the joints, which will lead to cracks at the connection points between the beams and the walls. Due to the appearance of the cracks, some concrete is out of work, with a qualitative change in the mechanical properties of the joints. Within a certain range, a proper increase in the axial pressure ratio can increase the energy dissipation capacity of the short leg shear wall joints, thus further increasing the ductility of the joints. For short torsional shear wall joints, which are easy to be torsional, the reinforcement layout of joints can be properly strengthened to withstand all external torsion and avoid premature destruction of joints.
