| 摘 要： | 目标可靠度指标是结构可靠性鉴定的基本依据 ,已有计算方法都没有考虑构件的抗力变化的影响 ,可能会导致结果偏于不安全。本文探讨了考虑目标使用周期不同和抗力随时间变化情况下 ,既有构件目标可靠度指标的计算方法 ,并给出了计算示例。

| Abstract: | Target reliability index is the basic reference for structure reliability appraisal.Current calculation methods do not consider structure resistance variation and thus may result in the paper,unsafe results.calculation method for the target reliability index of existing structures is in restigated,considering different target use period and resistance variatior with time. |
| |
| Keywords: | target use period resistance target reliability |
