| Abstract: | Based on the Cumulative Damage Theory,the concept of Exhaustion Index(EI) is put forward for bridge healthy assessment.Then,the model of ascent traffic intensity and overloading live load model is suggested according to the field survey.The case study shows the applicability of the algorithm.The recommended approach is used to identify the maximum deteriorated bridges in a certain rrgiou,for the purpose of further checking. |

| Keywords: | bridge healthy assessment exhaustion index(EI) traffic intensity equivalent load |
