Emergency Action Plan (EAP) is predicted reservoir failure scenario of action plans to protect or minimize life loss or property damages for residents in the downstream area under reservoir failure situation. Current EAP has included some of qualitative measures, such as, overflow expected, expecting over flood water level, etc., also training is not enough to folow EAP processes. Therefore, EAP must be renewed under consideration of new emergency action phases, quantitative measures and electronic manual.

This study was conducted to build an emergency action plan (EAP) for cable-supported bridges in South Korea. First, accidents happened on Cable-supported bridges were investigated and categorized based on the types. Second, accident scenarios were built-up regarding the types. Two bridges were selected for planning the emergency action following the accident scenarios. The emergency action plan established in this study could be used for the management of cable-supported bridges in the future.
