摘要：
The research presents a parametric experimental study on Low Strength Concrete (LSC) cylinders. The variables include the number of Carbon Fiber Reinforced Polymer (CFRP) layers and unconfined compressive strength of concrete. The aim is to predict the behavior of confined LSC cylinders and evaluate the enhancement in strength and ductility due to this external confinement with high strength CFRP wraps. The experimental results revealed a significant up gradation in compressive strength and ductility of CFRP wrapped LSC cylinders and showed a substantial contribution of this external confinement to the overall stability and stiffness of this composite system. The research concluded that various existing but seismic deficient concrete structures could be effectively strengthened with CFRP technique; which will not only recover their original state but also enable them to survive even larger potential earthquakes due to improved strength and ductility.
