摘要：
This paper is concentrated on the geometric nonlinear static analysis of the rib-hoisting for concrete filled steel tubular (CFST) long-span arch bridges. Applying the Updated Lagrangian Formulation (U. L. Formulation) a geometric nonlinear static finite element analysis program of cables, bars and beams is presented. Based on the progressive algorithm, the program of the finite element considering geometric nonlinear condition has been made to analyze the construction process of rib-hoisting for Nannidu Arch Bridge, which lies in Enshi city, Hubei province. The calculated value considering the nonlinear effect is very close to the measured value.
