Stability-based Risk Analysis for the Construction Phases of Long-Span CFST Arch Bridge

摘要：

Many researches have been done to evaluate the safety of constructed bridges and the uncertainties in the construction phases have been ignored. This paper adopts the 3D finite element program ANSYS to establish the space model of CFST Arch Bridge, and to calculate the linear, the geometrical nonlinear and the double nonlinear buckling safety factors under the six different lode cases. Then the bridges risks are evaluated according to the results calculated which provide a reference for design of similar project.
