해양성 환경에 위치한 RC 구조물의 현장조사에 의한 내구수명예측 시도

Attempt to Predict Service Life of RC Structures in Marine Environment by In Situ Investigation

The service life is defined as the period of the period of time, until repair becomes necessary to maintain the serviceability of structures. It is getting more common to specify the service life of a structure, particularly structures exposed to de-icing salt water. To accomplish this study, pier in the harbor was chosen as a experimental area. The service life of decks in marine environment was calculated as sum of three period ; initiation period, propagation period and cracking period. The object of this study is to indicate where and how measures can be adopted for checking relevant service lifes.
