摘要
Abstract
Flexible cable system is usually used as a longitudinal restraint in long-span steel bridges. Because of the large local stresses and complex load paths, specialized calculation and analysis must be proceeded to ensure the reliability of the anchorage structure in the design. In this dissertation, the finite element model for the anchorage structure of a long-span irregular-shape arch bridge is established to analyze the stress distribution of the steel anchor box under maximum cable force. The results show that the stresses of the steel anchor box under maximum cable force can satisfy the standard requirements and the structure remains in elastic state. The calculation and analysis of the arrangements of each panel of the steel anchor box are optimized and appropriate arrangement of anchor box stiffening plates is obtained.关键词
