基于动态可靠度的桥梁结构可靠度分析

On reliable analysis of bridge structure based on dynamic reliability

通过对某钢筋混凝土简支梁桥的基于动态可靠度的时变可靠度分析,较为完整地分析了该桥在服役期间的工作状态,并从恒载变异系数和活载变异系数等方面对该桥做了参数分析,为同类桥型今后的运营管理及加固改造提供参考。

According to the time variant reliability analysis based on the dynamic reliability of some reinforced concrete simply-supported bridge,the paper has the full analysis of the bridge＇s working status in its service period,and undertakes the parameter analysis of the bridge from the constant loading variation coefficient and the life loading variation coefficient,so as to provide some reference for the operation management and the consolidation reconstruction of similar bridges in future.
