Abstract

The method of reinforcing the structure by attaching the carbon fiber sheet started from the mid 1980's in EMPA in Switzerland. The research has been utilized in reinforcing many structures from 1990. The carbon fiber sheet adhesion reinforcing method is often difficult to completely adhere due to various reasons, and may fall off or peel off with the lapse of time. When reinforcement performance of a structure strengthened with a carbon fiber sheet decreases due to peeling of adhesion. Survey of many damage cases and theoretical study on the effect of detachment or peeling of carbon fiber sheet to the performance of the structure are needed to provide concrete solutions. This study analyzed the relationship between the separation of carbon fiber sheet and the performance of structures reinforced by carbon fiber sheet attachment method.
