FATIGUE TEST OF CONCRETE DECKS REINFORCED WITH CARBON FIBER SHEETS

With a total length of approximately 280-km, the Tokyo Metropolitan Expressway handles an average daily traffic volume of around 1.15-million vehicles and is used by roughly 2 million people every day. The structures have been exposed to the severe traffic conditions and with the passing of time several sections have begun to show sign of deterioration. In particular, there has arisen an anxiety that the defects of existing decks, which are directly influenced by live loads, will increase. The proper maintenance of the decks is an important issue. Thus, studies have been made on how to effectively repair or reinforce decks according to their severity of damage. Accordingly, the development of a new deck reinforcing method, which is more effective than conventional methods, has been required. Metropolitan Expressway Public Corporation, an administrator of the Expressway, has studied carbon fiber sheet reinforcement for the purpose of establishing repair and reinforcing methods for the decks. The objective of this study is to verify the effects and to establish rational design methods for carbon fiber sheet bonding. This paper introduces the method and present results of the fatigue test of RC decks with reinforced carbon fiber sheets.
