Abstract: This paper is aimed at exploring finite element modeling (FEM) method by reasonable structure discrete and boundary constraint choose, which can be suit for analyzing assembled steel truss-concrete composite continuously ridged bridge and reflect the characteristic of this kind of bridge, and using this method to analyze a bridge, the analysis results qualitatively agree well with the characteristic of the bridge, which means this method can be used to analyze this kind of bridge and worthy of expanding.
