Flexural Behavior of RC Beams Strengthened with Near Surface Mounted Prestressed FRP
프리스트레스를 도입한 표면매립 FRP 보강보의 휨 거동
Abstract
This paper presents the results of a study on improvement in flexure capacities of RC beams strenthened with near surface mounted prestressed CFRP rod and plate. Experimental variables include type of CFRP, prestressing level and existence of MI(Mechanical Interlocking). Tests show that prestressed beams exhibit a higher crack-load as well as a higher steel-yielding load compared to no-prestressed strengthened beams.
