【Abstract】 In order to study the optimal cross-section for steel-concrete composite open-web plate,this paper has established a finite element analysis model,an optimization parameter model and an optimization mathematics model of simply supported steel-concrete composite open-web plate.The cost of construction for a completed project was reduced by 24.7% with optimizing design.The optimization result indicates that this method is efficient in optimizing the section,so it could be applied extensively in the steel-concrete composite open-web plate section optimization design.The optimum of the steel-concrete composite open-web plate section was obtained after the optimization of different span plate.The impact of long-span ratio and design proposals of geometry size for the steel-concrete composite open-web plate were also discussed.更多还原
