摘    要:在荷载、环境和材料内部因素的作用下,钢筋混凝土结构的性能逐步劣化,结构的实际可靠度不断降低,基于混凝土碳化、混凝土保护层锈胀开裂和锈胀裂缝宽度3种不同的耐久性极限准则,提出了在役结构动态可靠度分析方法并对相关统计参数的取值进行了探讨.

关 键 词:功能函数  动态可靠度  统计参数  耐久性  在役结构  可靠性分析  durability  based  existing structures  analysis  取值  统计参数  相关  方法  动态可靠度  极限准则  锈胀裂缝宽度  开裂  保护层  碳化  混凝土  劣化  性能

Abstract:The performance of structures will deteriorate gradually with the actual reliability of structures reduced under the action of load, environment and interior factors of materials. Based on carbonization, corrosion expansion and crack width, the analysis methods of time-dependent reliability and relative statistic parameters were proposed.
Keywords:performance function    time-dependent reliability    statistic parameter
