Study on mechanical principle and combined structure of shear wall and swing wall in seismic design of high-rise buildings

Abstract

This paper studies the mechanical principle and combined application of shear wall and swing wall in the seismic design of high-rise buildings. Shear wall is a longitudinal wall perpendicular to the plane of a building, which resists the shear force generated by an earthquake through shear resistance, flexural stiffness, and contribution stiffness. Swing wall is a kind of seismic wall that can produce large horizontal displacement. Its mechanical principle is to improve the seismic resistance through flexible design, energy absorption and stiffness control. Shear wall and sway wall have advantages respectively, but they also have limitations respectively. By optimizing the layout and combination of shear walls and swing walls, give full play to their advantages and improve the overall seismic performance of the building. The effectiveness of the combined application is verified by the buildings with different seismic grades and structure types. However, this study has some limitations, such as the failure of the references to fully cover all relevant studies. Future research can further explore more new seismic structure systems, and combine with the latest materials and technology, and constantly improve the seismic design theory and practice of high-rise buildings. To sum up, shear wall and swing wall are a common structural system in the seismic design of high-rise buildings. By studying the mechanical principles and combined application, we provide new ideas and methods for the seismic design of high-rise buildings, which helps to improve the seismic performance and ensure the safety of personnel and property.
