Abstract

The application of BIM (Building Information Modeling) technology allows designers in the construction industry to complete their design work with lower energy consumption and higher efficiency and is therefore increasingly being used in other design fields. In this study, a finite element model of the concentrator was constructed using BIM technology to reduce the amount of steel used in the manufacture of the trough solar concentrator and thus reduce its production cost, and static analysis and steel minimization planning analysis was conducted. The analysis results show that the multiple linear regression algorithm is more reasonable to calculate the structural optimization evaluation index. The steel consumption of the *02 solution is lower, and the lowest values are 805. 962 kg and 3974. 9￥ for the total steel consumption and steel cost, respectively, which is 10. 99% lower than the steel cost of 4465. 5￥ for the concentrator before optimization. Although its maximum displacement and maximum stress are not the lowest among the alternatives, they are still far below the corresponding allowable values of the structure, so this solution has the best comprehensive optimization effect. The results of this research show that the application of BIM technology to the design of trough solar concentrators can indeed save equipment production materials and reduce production costs, and has certain application prospects.
