Abstract
In recent years, continuous fiber reinforcing materials are expected to use strongly for maintenance of concrete structures as repair or strengthening materials. Especially, CFRP strands are the most suitable materials as tendons, for example, ground anchor methods, external or inner cables of prestressed concrete structures, because CFRP strands have many superior mechanical properties obtained from our previous fundamental studies. The important mechanical properties of CFRP strands are high tensile strength, relaxation and fatigue characteristics as tendons. These properties have not been discussed quantitatively and qualitatively.
In this paper, the important mechanical properties of CFRP strands as tendons are summarized with new innovation. The abundant experimental data were reverent and a prerequisite for repairs, strengthening design as well as for the new construction design of concrete structures.
