Abstract

As the core load-bearing system of modern large-scale buildings, complex spatial steel structures play a pivotal role in enhancing engineering efficiency and quality through intelligent optimization technologies. This paper addresses prevalent issues in current steel structure joint design, such as low modeling efficiency, single-dimensional optimization, and frequent reinforcement layout conflicts, by proposing a comprehensive intelligent optimization framework integrating parametric modeling, intelligent algorithms, and BIM technology. The study establishes parametric reference models for steel frame joints, truss intersection joints, and hybrid structural joints, achieving high-efficiency modeling of complex nodes. By combining the NSGA-II multi-objective optimization algorithm with particle swarm formation optimization, a multi-objective optimization model is developed with stress uniformity, manufacturing cost, and construction convenience as core objectives. This approach significantly reduces stress concentration (by 26.8%) and fabrication cycle time (shortened by 37.5%). Furthermore, the research develops a construction-oriented reinforcement collision avoidance rule database and AI path planning algorithms, resolving spatial conflicts between reinforcement and steel components. Field measurements demonstrate a reduction in reinforcement layout conflicts from 45% to 2%. Application in the Chongqing Science City Auditorium project validates the system’s effectiveness: detailed design efficiency improved by 40%, installation errors were controlled within 3mm, and rework rates reduced to 1.2%. This provides a systematic solution for intelligent design and construction of super-large complex steel structure projects.
