Abstract
In the conventional reliability-based design method, it is considered that a structure has only two performance states whether normally operating or break down. In general, however, the performance of structure will vary with several patarns during its life time. In this study, the reliability evaluation of RC highway bridge pier is performed by the time series MSS (Multi-State System) which can be evaluated the reliability of structure with considering several time dependent performances. Concretely, multiple performance states of piers received salt damage are modeled by the time series MSS, and then the reliability is evaluated. Further, their results are compared with the results obtained by a conventional reliability method with considering only binary performance states.
