Steel Angles and Strips Jacketing of Existing RC Columns: A State of Art

Abstract

Steel angles and strips jacketing method is the popular structural local strengthening technique for existing deficient RC columns. Although this strengthening technique is well accepted, limited research is carried on the actual strength and behaviour enhancement of the deficient RC columns due to the application of this particular steel jacketing method. This study primarily intends to review the experimental and numerical works on the steel angles and strips jacketing method used for deficient RC columns available in published literature. This study also intends to present the variables which have considerable influence on the strength and behaviour enhancement of the deficient RC columns for this structural local strengthening technique.
