Abstract:
To research the stability of concrete-filled steel tubular(CFST)arch bridges with lateral displacement, and provide theory support to strengthening construction, the space calculated model was built to analyze the buckling and instability behavior of the bridge under various cases using finite element program. The results show that the strengthening measures, such as setting temporary fixing steel stringer and welding K-support bar on arch rib can greatly improve the stability of the bridges in all construction stages, and ensure the normal service after strengthening. The strengthening measures are effective and feasible, which can provide references for reinforcement design and construction of the same kind of bridges.
