Enhancing Shear and Flexural Strength of RC Beam Using Aramid Fabric

Abstract

This paper presents the flexural and shears behaviour of Aramid fabric reinforced polymer (AFRP)
strengthened reinforced concrete (RC) beams of M25 grade of concrete. The experimental program was
including strengthening and testing. Simply supported rectangular beam of size 150mm x 150mm x 1000
mm as well as various depth of beam such as 150mm,200mm,250mmmm strengthened with Aramid fabric
polymer sheets. Total nineteen specimens was tested. It was nine beam tested in flexural and 9 beam was
tested in shear strength. which are six beam specimens was tested as control beams and remaining for
founded various damage degrees . The results indicate that the load carrying capacity of beams will
significantly increased as the number of the layer will be increased.. In order to study the flexural and shear
behaviour of the beam, the specimens was only subjected to two point loading mechanism only. The beams
was wrapped with AFRP sheets in single layer and double layers along the different strength of the beam.
The present work including casting of beam . Thus it is a feasible method for strengthening and retrofitting
of RC beams.
