For the last decade many bridges and buildings have experienced flexural strengthening with the fiber reinforced polymer(FRP) bonding system, demands for increasing heavy traffic loads and the changing of the code application. Although a large number of studies have been concentrated on the academic and scientific research of the FRP strengthened R.C members, little is known about the considerations and checkpoints of the field application for the FRP strengthening. This paper focuses on the case studies of the conducted field applications with the CFRP-bar NSM system and CFRP sheet direct bonding system. It also gives brief introductions of the methods based on test results. By deriving the problems of the FRP strengthening system and their field application, this paper provides the basic considerations and check points to researchers and practicing engineers.
