Retrofitting of distressed structures is a major concern worldwide for researchers particularly against torsion. Determination of torsional strength of retrofitted RC beams “U” wraps is again a difficult task. The experimental program is taken up with 30 rectangular beams tested under pure torsion. Torque of such a “U” wrapped RC beam with other dimension and material cannot be derived from these experimental results. To compute the same; analytical method based on softened truss model of Hsu is employed with modification on material properties. Both experimental and analytical methods are unable to provide a single equation to quantify the torsional strength. To overcome the same, soft computing method MARS and WASPAS method is employed in the present investigation. The methods are easy and time saving.
