Abstract

Abstract

The numerical analysis model of mortise-tenon joint shear walls was established by using the finite element analysis software ABAQUS. The influence of different tenon structures on the mechanical properties of mortise-tenon joint shear walls was studied, and the comparative analysis was carried out from the aspects of shear wall mechanical properties, overall failure mode and local failure mode. The results showed that different contact models were established according to the force conditions of the new and old concrete interfaces, which could accurately simulate the interaction between the interfaces in the mortise-tenon joint shear wall. Setting mortise-tenon holes in the composite structure could improve the deformation capacity before the peak value of the mortise-tenon joint shear walls, and the bearing capacity and ductility decreased. The crack development at the bottom of the tensile side of the mortise-tenon shear wall with combined mortise-tenon structure increased, and the crack development at the root of the transverse bulge of the mortise-tenon plate and the central through hole was significantly reduced. In the limit state, the setting of composite mortise-tenon joint could significantly reduce the local compressive damage at the transverse bulge position of the mortise-tenon joint shear wall.
