在役钢筋混凝土桥梁结构的可靠度评估研究

Reliability Evaluation Study on Existing Steel Reinforced Concrete Bridge

我国现有大量的钢筋混凝土桥梁结构,随着服役时间的不断延长,均存在着不同程度的老化和破坏现象,因此对这些桥梁结构进行可靠度评估就显得非常重要。从可靠度评估和维修策略、基于时变抗力的可靠度分析、疲劳可靠度和动力可靠度几方面问题出发,对在役钢筋混凝土桥梁结构的可靠度评估进行探讨,可为工程实践提供有意义的参考。

There are a great many of existing steel reinforced concrete bridges there existing various degrees of degradation and damage to evaluate the reliability towards nance, reliability analysis based on along with time going by. It can be seen that it these bridges. Proceeding from reliability evaluation is important and maintetime-varying resisting force, fatigue reliability and dynamic force reliability, the reliability evaluation towards these bridges is discussed, which can provide significant reference for similar engineerings.
