摘要
以上海市外白渡桥大修工程为实例,利用轴载谱加载,以Miner线性积伤准则计算细节疲劳寿命,对大修方案设计中拟采用的钢桥面板体系进行疲劳验算,以确定现有设计能否满足使用功能要求,并根据计算结果优化结构设计.
Take Waibaidu Bridge reconstruction in Shanghai as an example,by using axle load spectrum and Miner cumulative damage rules,the fatigue life of each detail is calculated. The fatigue life of steel deck system in the reform design is checked to find out whether or not it can meet the using function. Finally,design is opti- mized based on the calculating results.
