Abstract

Abstract: The paper analyses damaging causes for fixed support of Chongqing Beibei Chaoyang Suspension Bridge in high temperature in August 1992.It put forward the idea for changing fixed support into finite displacement supper support based on site and analyses for structural intemal force.It is practical for engineering.

Key words: high temperature, support damage, finite displacement supper support, repair design

摘要： 分析重庆北碚朝阳吊桥在1992年8月高温时,使固定支座破坏的原因,在现场调查和结构内力分析基础上,提出了将固定支座改为有限位移橡胶垫板支座方案,实践证明是可行的.

关键词: 高温, 支座破坏, 有限位移橡胶垫板支座, 修复设计
