An Experimental Study on Behaviors of Beam-Column Joint Wrapped With Aramid Fiber

Abstract

Concrete is a composite construction material plays a vital role in the construction of the nation’s infrastructure. The failure of the structure are mainly due to the failure of the concrete in beam, column joints.In recent days more technical researches are going on to avoid the beam-column joints failure. In this experiment we add the aramid fiber to check the behavior of beamcolumn joints and externally wrapped with aramid fiber was test to failure. Using an arrangement which transfer horizontal moment to the joints of the beam-column through two opposite cantilever moment arms.Aramid fiber is a class of synthetic fibers and heat resistant. They are fibers in which the strength of the chemical bond can be exploited due to the reason the chain molecules are highly oriented along the fiber axis. The experimental work consist of casting RC beam-column joints in controlled beam-column joints, design for torsion beamcolumn joints, and fully wrapped with aramid fiber beamcolumn joints each 3 specimen and curing this specimen for 7,14,28 days and testing this test specimen under “Loading Frame”.
