Confinement of RCC Circular Columns through Intermittent MS Rings

Authors(2) :-Chaitanya Mishra, Dr. A. N. Patel

Strengthening of Reinforced cement concrete (RCC) columns has now become one of the areas of study in construction industry across the world. One of the deficiencies in RCC columns is the lack of lateral confinement and low energy absorption capacity. Researchers are working on the techniques by which such deficiencies can be minimized during construction stage. The strength, ductility and energy absorption capacity of Confined RCC columns during construction can be enhanced by providing external confinement by employing Mild steel rings. This paper deals with determining experimentally. The safe loads for various confining patterns of plain M.S. rings on circular R.C.C. columns and to establish relation between different grades of concrete (M-20,M-25) in circular R.C.C.columns with confining architectural patterns. For this the R.C. concrete circular column specimens of 150 dia. were prepared. 45 no. of specimens were prepared for M-20 grade of concrete & 45 nos. of specimens were also prepared for M-25 grade of concrete. This paper also deals with to evaluate the effect of % of steel in confined circular R.C.C. columns and study of various failure modes.
