Abstract
The optimization design of steel structure joint connections is a critical research topic in modern architecture and engineering, playing a significant role in enhancing the overall structural performance and construction efficiency. This study aims to improve the mechanical properties and economic viability of joint connections by addressing issues such as stress concentration and complex construction inherent in traditional methods. Through a combination of finite element analysis and experimental validation, a parametric modeling-based optimization design procedure is proposed, incorporating topology optimization algorithms to refine the geometric configuration of joints. The results indicate that the optimized joint connection significantly mitigates stress concentration while reducing material usage, achieving lightweight design. Furthermore, practical applications in engineering projects demonstrate the method's excellent feasibility and potential for widespread adoption. A key innovation of this study lies in integrating advanced numerical simulation techniques with engineering practice, offering new insights into steel structure joint design and promoting technological advancements in related fields.
