摘要 基于影响桥梁结构可靠度的基本因素,考虑恒载与汽车荷载效应的基本组合,通过推算汽车荷载在不同设计基准期内的统计参数,采用可靠度校准法对不同设计基准期下桥梁结构的可靠度进行分析。并由JC法计算不同破坏类型受力构件的目标可靠指标值与结构抗力均值。结果表明,目标可靠指标与设计基准期近似呈线性递减关系,不同基准期下达到同一目标可靠指标所需抗力均值与设计基准期近似呈线性递增关系。 Based on the probability characteristics of basic variable affecting the structure reliability,considering the basic combination of the effect of dead load and vehicle load,through calculating the statistical parameter of vehicle load in different design reference period,the reliability of bridge structure is analyzed under different design reference period according to the calibration method of reliability.The target reliability index and the mean of the resistance of different stress component are calculated by JC method.The results indicate that the target reliability index decreases and the mean of the resistance to achieve the same target reliability index increases linearly with the design reference period approximately.
