Automated Optimum Design of Light Steel Frame Structures in Chinese Rural Areas Using Building Information Modeling and Simulated Annealing Algorithm

Many manual calculations and repeated modeling are required during the traditional structural design process. However, due to high cost, rural buildings in China cannot be professionally designed verified by designers as urban buildings, their safety economy easily meet requirements. Building Information Modeling (BIM) technology intelligent optimization algorithms can effectively improve process reduce costs, but applications field of residential limited. Therefore, this paper presents an innovative framework that realizes light steel frame structures on BIMBase platform (widely used BIM software China, 2023R1.3). Based parametric library components built standardized component coding, completes rapid interaction between analysis software, SATWE. The improved two-stage simulated annealing (SA) algorithm is applied obtain a scheme meets requirements reduces material consumption much possible. Two prefabricated were analyzed evaluate efficiency proposed framework. results show feasibility Compared with methods, period reduced six times while maintaining comparable levels indicators.
