교량용 케이블의 안전성 평가를 위한 내구성 평가 등급 산정

In this study, the durability rating was evaluated to evaluate the safety of bridges considering the factors affecting the corrosion of cables in cable-stayed bridges and suspension bridges. Corrosion factors were considered for salinity, sulfur dioxide concentration and relative humidity. In addition, the durability level was calculated by applying the corrosion rates given in KS D ISO 9223 ~ 9226.
