Abstract
With the acceleration of urbanization and the development of construction technology, steel structure residences have attracted extensive attention due to their advantages of being lightweight, high-strength, and convenient for construction. However, their seismic performance still requires further optimization to meet the safety requirements under complex seismic conditions. This study aims to systematically analyze the seismic performance of steel structure residences and propose targeted optimization design schemes. Based on the finite element analysis method and combined with actual engineering cases, various typical steel structure residence models were constructed. By simulating the dynamic responses under different seismic wave input conditions, the overall stability and local weak links of the structures were evaluated. The research findings indicate that the seismic capability of steel structure residences can be significantly improved through the rational arrangement of bracing systems, optimization of joint connection methods, and the introduction of energy-dissipating vibration-reducing devices. It is concluded that fully considering the characteristics of seismic action and adopting scientific optimization strategies during the design phase can effectively enhance the seismic performance of structures, providing theoretical basis and technical support for relevant engineering practices. The innovation of this study lies in comprehensively considering the influence of structural forms, material properties, and construction details on the overall seismic performance, and proposing optimization design principles with general applicability.
