An Experimental Investigation of Carbon Fiber Plates Used for High Strength Reinforced Concrete Beams
Received Date: January 27, 2020; Published Date: February 11, 2020
Carbon fiber plates (CFPs) have been used sufficiently to strengthen reinforced concrete structures and is becoming an increasing familiar approach amongst structural engineers. In this research investigation, four-point bending flexural tests were carried out to four full-size High Strength Reinforced Concrete (HSRC) beams without CFPs and four full-size HSRC beams strengthened with CFPs. All beams were subjected to short term static loads. The experimental test results presented herein showed that the use of CFPs had remarkable effects on the ultimate carrying capacity and the structural behaviour of all beams tested. In addition, the stiffness of RC beams strengthened with CFPs have increased significantly.
