Experimental and analytical study on torsion behavior of RC beam strengthened with GFRP laminations.

Abstract

Fiber reinforced polymer (FRP) as an external reinforcement is used extensively to enhance the strength
requirement related to flexure and shear in structural systems. But the strengthening of members subjected to torsion is
yet to be explored as Torsion failure is a brittle form of failure. In present study experimental and analytical study on
torsional strengthening of RC beam with GFRP lamentation. Total six rectangular beams of size 180*230 and length
1500 mm are casted. Out of six beam one beam as control beam and remaining five beams are GFRP wrapped beam at
different configuration. Numerical work was carried out using non-linear finite element (FE).
