摘要
钢-混凝土结合梁由于其突出的综合效益优点已经在土建工程中得到大量的应用,但就其具体分析而言,加载荷载多参照国外规范执行。基于广州市内环线某路段实测的交通量调查结果,推导出了该路段高架桥的标准车辆荷载谱加载,利用MSC.Fatigue对桥梁整体和局部进行了疲劳寿命评估。
With remarkable economic comprehensive benefit, steel and steel fibrous concrete composite box girders are broad doped in civil engineering. For particular analysis, most of the using load consults a square of foreignStandardsandcodes. A standard vehicular load spectrum derived of traffic volume survey Based on observation is aoped, and evaluating fatigue residual life of bridge is being proceed for global and local of bridge structure using the software MSC .Fatigue in this paper.
