Abstract: The finite element analysis software is used to analyze and calculate the stress of a long-span concrete-filled steel tube arch bridge in the construction stage, the limit state of bearing capacity in the operation stage, the limit state of normal use, and the dynamic characteristics. The results show that the strength, stiffness, stability and seismic performance of the bridge in the construction and use stages can meet the requirements of the current specifications, and has a certain safety margin, which indicates that the bridge structure design is safe and reliable. It provides a useful reference for other similar bridges.
