Abstract

The objective of this study is to propose prediction equations for performance parameters of Glass Fibre Reinforced polymer (GFRP) strengthened High Strength Concrete (HSC) beams. To examine the effectiveness of GFRP on high strength concrete beams, a total of fourteen beams of size 150 x 250 x 3000mm were cast and tested. All the test specimens were subjected to static and cyclic loading upto failure, in a loading frame of capacity 250kN. Necessary measurements were taken for each load increment. The proposed equation shows higher accuracy for predicting the performance parameters of high strength concrete beams strengthened with GFRP laminates.
