Abstract: Abstract Wrapping reinforced concrete (RC) column with FRP sheets enhances compressive strength and ductility of column. Since stress–strain curve of FRP-strengthened concrete is different from stress-strain curve of normal (un-strengthened) concrete, relations presented by codes… read more here.
