A strengthening method that was used quite extensively during the mid-1970s is steel plate bonding, this method has gained a renaissance in the last decades.This paper presents experimental work including an investigation of four simply supported reinforced concrete beams under pure torsion.The first beam Jars was the control beam without strengthening.

The other three beams were strengthened externally by bolted steel plates.The most important variable was the spacing between shear connectors.The discussion of results is based on torque-twist behavior, beam longitudinal elongation behavior, and the influence of the spacing between shear connectors on cracking Dab Rigs torque, ultimate torque, and failure modes.
