Study and Numerical Analysis on Seismic Performance of Concrete U-Shaped Shear Wall

Rectangular, L-shaped, and T-shaped section concrete shear walls in high-rise buildings are more frequently used in engineering and are widely studied. However, there are few studies related to the load-bearing performance of concrete shear walls with U-shaped sections. In this article, the seismic performance and damage mechanisms are analyzed in a systematic manner. In addition, a finite element model was developed using ABAQUS software, and numerical simulation was carried out. The damage forms and load-carrying capacity of shear walls with U-shaped sections were validated. Finally, reasonable suggestions and construction measures are given for the design of shear walls with U-shaped sections, and a benchmark is provided for relevant engineering applications.
