Evaluation and modeling of structures behavior over their service life are crucial parameters for construction safety. This research investigates the use of output-only structural health monitoring (SHM) to evaluate the reliability and safety of highway steel plate girders of WonHyo bridge. Displacement, strain and acceleration measurements were used to assess the bridge behavior under the designed static, semi-static and dynamic truck loads effects. A novel integration method with combined probability, Autoregressive and Integrated Moving Average (ARIMA) identification model was developed to design PARIMA approach, which is introduced and used for analyzing the semi-static and dynamic reliability of the bridge girders. The PARIMA experimentally evaluated structure's reliability and damage based on the output only SHM system. The results showed the effectiveness of PARIMA for detecting structures damages and analyzing structure's reliability in semi-static and dynamic domains. The evaluation of WonHyo bridges showed its performances in time and frequency domains are safe, and the bridge reliability is high.
