A Comparative Study of Steel Angles and Strips Strengthened RC Columns

Retrofitting is required for the structures which undergone strength deterioration by seismic events or have to sustain additional applied loads. Steel angles and strips jacketing is a quick and effective method to restore the strength of columns. Several researchers addressed the effectiveness of this jacketing method on columns through experimental works. Some researchers intended to pave the way of design procedure of strengthened RC columns by formulating compressive capacity prediction models. This study primarily intends to review the experimental works and analytical models available in the literature. Finally, a comparative study has been conducted considering available parameters in literature to identify the key parameters, which have influences in a large extent on the compressive strength of steel angles and strips strengthened RC columns.
