Abstract

In a multi storey building columns are very important structural elements The foundation has the transmission of entire loads. The load carrying capacity of the compression member has to be increased by confining the columns. There are a lot of confinement techniques that are used for strengthening of concrete structures. Ferrocement, glass fiber, aramid fiber, carbon fiber, etc. are some of the few materials that are used in the confinement of concrete columns. Reinforced concrete jacket around the existing structural member is one way of section enlargement. Enlargement is the placement of to achieve the desired sectional properties and performance. This experimental study aims at assessing the behavior of such reinforced concrete columns confined with external Reinforced Concrete jacketing technique. This would enable in arriving at the effectiveness of the confinement in concrete columns in seismic regions. Strengthened columns are tested under axial loading to study the behavior of RC Columns strengthened with RC Jacketing technique.
