Analytical Model for Construction of Interaction Diagram for RC Columns Strengthened by Steel Jacket

Mohannad H. Al-Sherrawi [4] | Hamza M. Salman

Abstract: Different methods used for repairing or strengthening of RC columns. Strengthening with steel jacket is widely used specially for rectangular and square columns. Many studies have been carried out on this technique, most of these studies did not take the effects of bending moments into consideration. This paper presents analytical models to construct the axial load-bending moment interaction diagram of a RC column strengthened with steel jacket. The models include the confinement produced by the steel jacket into consideration. The derivation of expressions was made by assuming equivalent stress block parameters for confined concrete. The proposed models show good agreements with available experimental data. In addition, the results of proposed models were compared with design proposals and illustrate good agreement.
