A Experimental Study on the Flexural Characteristics

GFRP로 보강된 RC보의 휨특성에 관한 실험적 연구

Flexural tests on 2.4m long reinforced concrete beams with epoxy-bonded GFRP plates are reported in these tests. The selected experimental variables are strengthening plate length, plate thickness, plate width and the method of anchoring the plate ends. The effects of these variables in overall behavior are discussed. The results generally indicate that the flexural strength of strengthened beams is increased. The ductile behavior of tested beams in inversely proportional to the plate thickness, plate width. The use of an U-jacket plate provided a proper anchorage system and improved the ductility of beams.
