摘要
采用有限元软件MIDAS/Civil建立模型,分析了拱肋和拱肋间横撑对某提篮拱桥稳定性的影响,从分析结果可以看出,减少拱肋的横撑,结构的稳定系数将减小,其中采用K撑的拱肋的稳定性比采用一字形横撑的稳定性要好。
The paper adopts finite element software MIDAS/Civil to establish models,analyzes the influence of the brace between the arch ribs on the stability of some basket handling arch bridge,proves by the analysis results that the reduction of the brace leads to the reduction of the stability coefficient of the structure,and indicates the stability of the arch rib with K brace is better than the straight line brace.
