Environmental degradation, increased service loads, lower capacity due to ageing, degradation due to poor construction materials and workmanship, and the conditional requirement for seismic retrofitting have all necessitated the need for existing structural maintenance and rehabilitation. Fiber reinforced polymers were employed. Because of factors such as low weight, great strength, and durability, it has been used successfully in a variety of such applications. a number of previous Torsion strengthening research has primarily focused on solid rectangular RC beams with varying strip thicknesses.

Patterns and various fiber kinds several analytical models have been devised to predict the torsional behavior of reinforced square beams and successfully used for experimental work validation. However, literature the research on torsional strengthening of RC T-beams is limited. In the current work, an experimental study was carried out in in order to have a better knowledge of the torsional strengthening behavior of solid RC flanged T-beams. An RC T-beam is analysed and designed for torsion in the same way that an RC rectangular beam is; codes ignore the effect of concrete on flange. The effect of the flange part in resisting torsion is investigated in this study by varying the flange width of controlled beams. Strengthening configurations and fiber orientations are two more characteristics being investigated.
