A method to optimize the topology of grillage structure with stress constraints is presented. 提出一種應力約束下的格柵結構的拓撲優化方法。
Based on coordinating relations of steel and concrete, the grillage structure finite-element method was adopted to analyze the space mechanical effect of curved girder bridges. 本文針對曲線梁橋空間力學分析的複雜性,提出了採用基於鋼混協作關係的格柵結構有限元法來分析曲線梁橋的空間力學效應。
