| Abstract: | This paper establishd a spatial calculation model for box-arch by finite element program ANSYS for the purpose of mechanical analysis of concrete arch bridge with stiffness frame of small steel tubes during the construction. On the basis of the analysis of stress and deflection of the arch bridge during the construction by internal forces superposition method and stress superposition method, the paper compared the characteristics and adaptable ranges of the two methods, and discussed the influences of initial stress and sectional stiffness on mechanical analysis of the arch bridge. |
