| 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 steelconcrete 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. |
