A new type of large-size reinforced tenon precast shear wall was proposed, which can effectively reduce the pin-key shear stress of the longitudinal connecting steel bars and improve the seismic performance of the precast shear wall. In order to study the bending-shear separation mechanism of the wall edge restraint member and the reinforcement-slotted shear, this paper first proposes the bending-shear separation mechanism of the wall edge restraint member. The concept of bending-shear separation degree was introduced, the mechanical analysis model of reinforced tenon was established, and the calculation method of horizontal relative slip of reinforced tenon interface was obtained by using Rayleigh-Ritz variational method. The relationship between horizontal relative slip of interface and shear stress of steel pin key was established, and the size of large-sized reinforced tenon to interface was studied.
