Highway bridges have been collapsed due to vehicle collisions over last few decades, which led to social and economic costs such as traffic controls, detour construction, and etc. The anti-collision devices are designed in order to reduce damages caused by vehicle collisions. However, increasing traffic density leading to high risk of vehicle collision with existing bridge piers requires countermeasures to lower risk of vehicle collisions. This study aims at assessing vehicle-pier collision risk level of bridges and proposing countermeasures for the high risk bridges.
Risk analysis consist of three steps, Preliminary Risk Analysis (PRA), Simplified Risk Analysis (SRA), and Detailed Risk Analysis (DRA). PRA (Preliminary Risk Analysis) is performed determining whether the risk analysis is needed. In the second step, SRA (simplified risk analysis) is performed on the bridges that the risk anlaysis is needed from PRA step. In the SRA, risk analysis is performed by occurrence, vulnerability, and importance of a bridge, and risk score was calculated by three factors. Lastly, risk level is classified into three grades; Low Risk (RL), Moderate Risk (RM), and High Risk (RH) for the risk level through risk score. Four of classified method is Natural Break based Interval (NBI), Equal Interval (EI), Standard Deviation based Interval (SDI) and Reliability based Interval (RI). In the third step, detailed risk analysis(DRA) is performed to degrade risk level only applied to RH-graded bridges on the risk level. Supplemented bridges have the risk grade re-evaluated. In this study, DRA was not conducted by the lack of detailed documentation of the bridge.
