Abstract |
An experiment of composite beam was performed which utilized glass fiber reinforced polymer (GFRP) plank as the permanent formwork with cast-in-place high strength concrete. This research analyzed the flexural failure behavior of composite beam by setting the sand coated at GFRP bottom surface, the perforation and interval of the GFRP plank web, and the width of the top flange as the experimental variables. As a result of the experiments for effectiveness of sand attachment in case of not perforated web, approximately 43% higher ultimate load value was obtained when the sand was coated than not coated case. For effectiveness of perforation and interval of gap, approximately 23% higher maximum load value was seen when interval of the perforation gap was 3 times and the fine aggregate was not coated, and approximately 11% higher value was observed when the perforation gap was 5 times on the coated specimen. For effectiveness of top flange breadth, the ultimate load value was approximately 12% higher in case of 20mm than 40mm width. |
