Abstract

The local structure of the outer web of a cable-beam anchorage area and the steel anchor box sub-model of a long-span cable-stayed bridge were established by using the sub-model modeling technology of Ansys software, and the structural strength analysis was completed. The results show that the stress concentration of the steel anchor box in the cable-beam anchorage area is serious, and the maximum stress value exceeds the yield limit of the material. Therefore, according to the stress concentration area of the steel anchor box structure, the local structure is optimized. The improved scheme obviously reduces the stress concentration of the structure, and the research results can provide a reference for the design of the anchor box structure of the same type of bridge.
