| 摘 要： | 根据服役结构的特点，提出了服役结构抗力的非平稳随机过程模型。考虑结构在服役过程中的耐久性损伤对构件承载力的影响，建立了预测抗力平均值和标准差的数学模型。以服役钢筋混凝土受弯构件为例，具体分析了抗力平均值和标准差随时间变化的规律。

| Abstract: | Based on the features of existing structure, the nonstationary random process model of resistance for existing structure is proposed. Considering durability damage of serviced structural elements, the predicting model of the mean and standard deviation of resistance are built. The reinforced concrete flexural member of service is taken as an example in the specific analysis on the mean and standard deviation of resistance which varies with service time. |
