Abstract

Strengthening reinforced concrete columns (18) by using Fiber Reinforced e Polymer (FRP) composites can b an effective method of retrofitting existing columns. FRP composites have a number of advantages over steel, including their high strength-to­-weight ratio and excellent durability. The confinement effectiveness of FRP materials for rectangular sections can be improved by performing shape modification such that a rectangular column section is modified into a shape that does not have 90 degree corners such as an elliptical, oval or circular column. An expansive concrete (22) can be advantageously used between the FRP material (26) and the existing concrete (18) in order to post-tension the FRP material circumferentially and improve confinement of the concrete. A finite element analytical model is also disclosed which model describes the stress-strain relationship for the FRP-confined columns after shape modification.
