Behavior of Rectangular Concrete Column Confined with Sisal Fiber Reinforced Polymers (Sisal FRP)

Abstract

This research work presents the results of experiment study on the axial behavior of low-high strength concrete rectangular columns confined by Sisal Fiber Reinforced Polymers (Sisal FRP). The objective of this study is investigate the performance of Sisal FRP composites to increase strength and ductility of rectangular columns through external confinement. The research parameter were confinement thickness and strength of concrete core. A total of 16 rectangular columns were tested under Universal Testing Machine (UTM) up to failure point. Test result shown that the external confinement by Sisal FRP are very effective to increase strength and ductility.
