| 摘 要： | 既有混凝土桥梁结构在荷载、环境、材料以及使用时间等因素的影响下,结构的性能会逐步劣化,结构性能的劣化使得结构的实际可靠度比原设计的可靠度降低.而既有结构可靠性指标逐渐下降的过程是一个动态的过程.论述了考虑抗力变化的结构动态可靠度,提出了结构动态可靠度的分析计算方法.此方法简便易行,且形式上能够与现有的结构可靠度分析方法相协调,因而可以作为既有混凝土桥梁结构可靠度分析的参考方法. |
| 关 键 词： | 既有混凝土桥梁 动态可靠度 抗力衰减 |

| Abstract: | Under the influence of loading,environment,material and service time,the existing concrete bridges structure performance can gradually deteriorate,which makes the actual reliability of the structure reduce than the reliability that is designed originally.The reliability target gradually drops is a dynamic process.The dynamic reliability of structure considering resistance changes is expounded,and the analysis computational method of the structure dynamic reliability is proposed.This method not only is simple and convenient,but also can coordinate with the existing structure reliability analytical methods in the form,therefore it can be used as a reference method for the reliability analyses of the existing concrete bridge. |
| Keywords: | existing concrete bridge dynamic reliability resistance deterioration |
