외부 프리스트레싱과 CFRP 쉬트로 보강된 PSC 보의 실험적 연구
Experimental Study on PSC beams Strengthened by Externally Prestressed Tendons and CFRP Sheets

초록
Bridges are deteriorating over service life due to over weight vehicles, environmental conditions and so on. In addition to that, those could be classified into low level bridges which are not fit for highway because of upgrade of the design load. Consequently, such reasons impel the bridges to be repaired or strengthened. Among the rehabilitating methods, FRP sheets and externally prestressing methods are preferred recently. This paper presents experimental results about the behavior of PSC beams strengthened by external tendons and CFRP sheets.
