摘　　要：分析了服役结构可靠性计算中的抗力随机时变性影响因子 ,研究了基于样本值的抗力概率特性的Bayesian方法。提出了基于检测的样本值的服役结构抗力的随机时变模型 ,可较为简便和有效地进行服役结构可靠度分析中的抗力估计。In this paper, influential factors of stochastic time-dependent of resistances for reliability calculation of existing structures are analyzed, and Bayesian method for probable characteristics of resistances is studied based on sample value. Based on measured sample value, a resistance model of stochastic time-dependent for existing structures is proposed, which can estimate conveniently and effectively the resistance for reliability analysis of existing structures.
