Today’s world is demanding tallest structures; engineering marvels for that we need an material having very good strength. Considering this many times fiber reinforcement polymer (FRP) grade material is used as an external reinforcement extensively. But the major problem is strengthening members are subjected to torsion is exploration started very recently. In earthquake prone areas, concentration at torsion failure is very important. In the experimental step up, behavior and performance of concrete beams rectangular in shape is strengthened with externally bonded GFRP (glass fiber reinforced polymer) for study of torsion. Experiment was performed on rectangular RC beams bonded with GFRP. This set was under test to identify to detect effect of transferring transfer torque to central part of the beam using cantilever situated at opposite arms. Every arm in the set up was situated under some static load. This was destructive type of testing require and all beams are designed to get pro https://journalnx.com/journal-article/20150020
