Numerical Analysis of Seismic Behavior of a Concealed Bracing Connection for Precast Concrete Shear Walls

Abstract:

Aiming at the horizontal connection joint of the precast shear wall structure, this paper presents a new-type horizontal wall-to-wall connection. Based on the ABAQUS finite element analysis platform, an accurate finite element model of shear connection joints was built. By quasi-static numerical tests, the seismic behavior of the proposed connection of the precast shear wall system was analysed and compared with that of the traditional cast-in-place connection. The numerical results show that the seismic performance of the presented connection, such as deformability and energy-dissipation capacity, is slightly lower than that of its cast-in-place counterpart.
