Flexural capacity of prestressed concrete beams reinforced with aramid fiber reinforced polymer (AFRP) rectangular tendons

摘要

The use of fiber reinforced polymer (FRP) composites is significantly growing in construction and infrastructure applications where durability under harsh environmental conditions is of great concern. Aramid fiber composite rectangular tendons have potential as reinforcements for concrete structures. Recent studies on prestressed concrete beams have showed brittle flexural failure due to the elastic rupture of the FRPs; however, for the maintenance and hazard anticipation of structures, the brittle failure mode is undesirable.
