Strengthening Effect of Prestressed Near-Surface-Mounted CFRP Tendon on Reinforced Concrete Beam

Table 3

Types of anchor for CFRP tendon.

Anchor type	Wedge	Bond	Swaged
Image
Characteristics	Shortest anchor length; Wedge stress concentration	Need sufficient anchor length; Low-cost fabrication possible; Remarkable adaptability to change of the diameter of tendon	Possibility to shorten the anchor length; High fabrication cost; Need for special equipment
Anchor length	60 mm (except sleeve length)	400 mm	150 mm (after compression)
