N2  - A residual service life prediction method based on critical life curves of selected bridge members is presented in this paper for bridges in service. The lowest target reliability index is selected as the criterion for the end of the lifecycle of bridges based on bridge design codes. Based on various assessment reference periods, a simple stochastic process model of resistance is adopted to evaluate corresponding resistance reduction coefficients related to the adopted lowest reliability index. By proposing the critical life curves based on flexural resistant capacity, the paper established a new method to predict the residual service life of bridges. A case study is used to demonstrate the proposed approach. The authors inspected 11 pieces of 13-m hollow-core slab beams that had been in use for 11 years. The accuracy of the prediction method was verified through a field condition investigation and a lab destructive test on a beam dismantled from the studied bridge.<p /> <p>Language: en</p>
