Outline
Corner concrete damage and failure in shear wall structures under seismic loading is one of the primary factors leading to degradation of overall structural performance. This study focuses on steel-concrete modular prefabricated composite shear walls, proposing four optimized corner design schemes: curved steel thick-plate (CSTP) design, stiffened CSTP design, folded steel thick-plate (FSTP) design, and stiffened FSTP design. The seismic performance of these optimized designs was compared with that of non-optimized composite shear walls, followed by an investigation into the parameter influence patterns of the optimal design. Results demonstrate that all four corner optimization schemes enhance the seismic performance of modular prefabricated composite shear wall specimens, with the stiffened FSTP design showing the most significant improvement. This optimal design substantially improves the collaborative working capacity of the structure, increasing initial stiffness, peak bearing capacity, cumulative hysteretic energy dissipation, and ultimate drift angle by 40%, 43%, 44.7%, and 23.58%, respectively, compared to the non-optimized scheme. Optimal parameter ranges for the stiffened FSTP design are provided, offering references for practical engineering applications.
