摘要：

According to the interval characteristics of action effects presented in bridges on service, the non-probabilistic reliability theory based on convex model and its application in bridge engineering were highlighted. Three calculating schemes of non-probabilistic reliability, including definitional procedure, transformational one and optimal one, are presented. The general steps of non-probabilistic reliability assessment of bridges on service were discussed. Then the application was carried out in a real bridge. Furthermore, the time-varying reliability analysis and life forecast of bridges in active service were performed. The results show that non-probabilistic reliability assessment of bridges on service is feasible and reasonable when available data are limited.
