Polyacrylonitrile(PAN)-based carbon fiber is a new building material used for reinforced concrete. Its density is only one fourth of reinforcing steel bar''s,while its tensile strength is 10times of the steel bar''s,and its properties are better. Its application value is admitted by the industry. The flexural capacity and the shear capacity of PAN-based carbon fiber composite reinforced concrete, and the design and construction application of aseismatic reinforced concrete column are detailedly introduced.
