“…The study took into account factors such as the dimensions of the wall limbs, coupling beam sections, number of stories, and coupling ratios. Hao Jiping et al [14] introduced a seismically resilient coupling system for steel plate shear walls, known as C-SPSWS, and conducted an analysis of its seismic performance. Tian et al [15] used finite element software to analyze the seismic performance of composite steel plate and ordinary concrete coupling beam shear wall structural system.…”

This paper based on the study of steel plate-fiber reinforced concrete coupling beam components, designs a basic model of composite coupled shear walls with steel plate-fiber reinforced concrete coupling beams. The seismic performance of this model was numerically simulated using the ABAQUS finite element software, analyzing the stress distribution of various parts and the development pattern of plastic hinges in the structure. It also examines how factors such as axial compression ratio, coupling beam cross-sectional dimensions, single-sided wall limb aspect ratio, and total floor height affect the seismic performance of this type of coupled shear wall, providing a reasonable range for axial compression ratios and coupling ratios for composite coupled shear walls with steel plate-fiber reinforced concrete coupling beams. Based on the obtained reasonable axial compression ratio and coupling ratio, and using the analytical solution of the continuum method, a method for controlling the seismic performance of coupled shear wall structures was proposed. Results show that the composite coupled shear walls with steel plate-fiber reinforced concrete coupling beams exhibit high load-bearing capacity and lateral stiffness under inverted triangular horizontal loads, with good displacement ductility and strong energy dissipation capability, making it an excellent seismic performance coupled shear wall system. As the axial compression ratio increases, the displacement corresponding to the yield point and peak point of the structure gradually decreases, and the displacement ductility coefficient shows a trend of first increasing and then decreasing; it is recommended that when designing steel plate-fiber reinforced concrete coupling beam-coupled shear walls, the axial compression ratio should not exceed 0.3. Numerical analysis of coupling ratio-related parameters indicates that in high-intensity seismic design areas, the range of coupling ratios should be between 45% and 60%.

“…In the process of modern building construction, in order to increase the seismic ability of the wall, the wall is usually divided into several wall units. Through the mutual restriction of the shock absorber between the wall units, the damage to the wall is reduced [1].…”

Assembly type buildings is a new form of buildings in our country. It can build quickly and lower cost of production. In order to study the seismic performance of prefabricated structural wall, based on the analysis of the structure composition of the existing seismic wall, through the practical project, Vanke Metropolitan Jinyue Yuan No.6 building, the finite element model of prefabricated wall building was established by ANSYS. The wall unit comprises a wall panel and a lower fixed assembly, a connecting assembly between two wall panels, and a connection limit for two wall panels is implemented by providing a connecting plate. It is analyzed whether the seismic performance of the vibration mode, stress and strain of the new aseismic wall conforms to the requirements of the relevant codes, and further adjustment is made. Using the finite element analysis software, six finite element models with different vibration modes are established and calculated. The failure modes and seismic performance of the models are basically the same as the expected experimental results, which verify the effective seismic performance of the finite element model.
