Strengthening of reinforced concrete columns using FRP fabric

In a number of cases, the compressive strength of reinforced concrete members have been found to be less than the design strength. Therefore, forcing the structural engineer to strengthen these members in order to cater for the dead, superdead and superimposed loads to which these structural members...
