Abstract/Summary

Jacketing is a common engineering practice in order to repair and strengthen deteriorating RC columns. In this study, the proposed method of jacketing is through the use of mortar reinforced with steel fiber. Using steel fibers as a reinforcing material to the jacket, the effect on the columns load carrying capacity was tried to be studied.

The study has considered 120 mm x 120 mm columns coated with a uniform jacket that is 10 mm thick. The jacketing material consists of Steel Fiber Reinforced Mortar (SFRM) having three considered volume fractions specifically 1%, 2%, and 3%. Through the use of the Universal Testing Machine (UTM), these jacketed columns were tested until failure after which the load-strain diagrams were plotted. The load resisted by a column is only carried by three materials, namely: concrete, steel and SFRM. The computed carried load of each of these materials through their actual strains does not consider confinement thus, the actual load resisted by the column subtracted by the unconfined load contribution of each material have quantified the confinement effect.
