Study on Vertical Joint Performance of Single-Faced Superposed Shear Wall Based on Finite Element Analysis and Calculation

In this paper, a new type of single-faced superposed shear wall system is proposed based on the single-faced superposed shear wall structure. The nonlinear finite element analysis of a new splicing form of single-faced superposed shear wall components is carried out by using the method of combining experimental research and ABAQUS finite element software analysis. The impact of noncolumn on the connection performance of vertical seam is studied. The analysis shows no significant difference in the effect of eliminating concealed column on the hysteretic performance and bearing capacity of the single-faced superposed shear wall with the joint. The single-faced composite shear wall with two different splicing forms presents bending-shear failure. The single-faced composite shear wall model without concealed column design can also maintain good overall performance and seismic behavior.
