Review Study on re-strengthening of reinforced concrete circular column using steel strips
Abstract: This technique fixes thin steel plates i.e. steel encasement or tie plates i.e. steel cage around the column with steel angles at each corner, clamped to the concrete and welded together. Adequate tightening of the jackets can be ensured by means of heat tensioning. The use of steel jackets can enhance the shear strength of columns considerably. However, due to their low flexural stiffness they typically have poor confinement efficiency …
