Carbon fiber reinforced polymer retrofit for columns

CFRP wrapping concrete columns can effectively improve the axial compressive bearing capacity of the columns. The use of CFRP can significantly increase the compressive strength of concrete and improve the ductility of concrete. At the same time, for concrete structure reinforcement and reconstruction projects, CFRP reinforced concrete column technology has many advantages (high strength and ...
