Abstract
Strengthening concrete structures with fiber reinforced polymer materials have grown to be a widely used method over most parts of the world today, which FRP was developed in 1960. A method to apply prestressing force to FRP is developed newly in these days, which can use the maximum performance of FRP materials. This paper presents the results of a study on improvement in flexural capacities of RC beams strenthened with near surface mounted prestressed CFRP rod and plate. Experimental variables include type of CFRP, prestressing level. Tests show that prestressed beams exhibit a higher crack-load as well as a higher steel-yielding load compared to non-prestressed strengthened beams.
