Seismic Performance Assessment of Bolt Connection-based Assembled Composite Shear-wall
In order to promote the process of building industrialization, this paper proposes a horizontal joint connection form of assembled composite shear-wall based on bolt connection and uses ABAQUS software to carry out nonlinear experimental analysis. Through comparing the stress nephogram, skeleton curve, hysteretic curve, ductility, stiffness and energy dissipation of cast-in-place and composite specimens, the reliability of the seismic performance of new assembled composite shear-wall is verified. In addition, the influence of the inner steel-plate strength and axial compression ratio on its seismic performance is discussed preliminarily. The results show that the horizontal joint connection method of the new assembled composite shear-wall can effectively transfer the load at the joint and is a reliable connection method. Due to the horizontal joints, the seismic performance of assembled specimens is lower than that of cast-in-place specimens. Furthermore, with the increase in steel-plate strength and axial compression ratio, the load-bearing capacity of assembled specimens continues to improve, but the ductility is weakened. Combined with the finite element analysis results, a calculation method for the flexural bearing capacity of composite shear-wall based on the superposition principle is proposed, and the calculated values agree well with the simulated values.
