Abstract – In recent years Fiber Reinforced polymer gained wide use of strengthening and repairing works for the beams columns and slabs of buildings and bridges. FRP is commonly used in the aerospace, automotive, marine, construction industries and ballistic armor.  The present study is mainly focused on the investigation of the effect of externally bonded FRP upon the strength characteristics of R.C columns. Large number of studies on R.C columns wills shows that the column will fail due to improper or insufficient confinement. In case of FRP, it will provide effective confinement to the column, this property of FRP makes it much suitable as strengthening material. So I had planned to study the effect of FRP on strength and durability aspect of RC column. For this purpose 6 RC circular columns, dimensions 300mm height and 150mm diameter are to be considered. Among the 6 specimens, 2 will be confined with FRP wraps of single layer (3mm thickness), another 2 are confined with FRP wraps of double layer (5mm thickness) and the rest were unconfined and are tested for compressive strength and deflection using dial gauge. The axial bending of casted short column is wrapped with double layered FRP was performed and monitored, and a cracked section of short column was repaired using FRP and checked.
