【摘要】 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。更多还原

【Abstract】 There are a great many of existing steel reinforced concrete bridges there existing var-ious degrees of degradation and damage along with time going by.It can be seen that it is important to evaluate the reliability towards these bridges.Proceeding from reliability evaluation and mainte-nance,reliability analysis based on time-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.更多还原
