AASHTO CFRP-1, Guide Specifications for the Design of Concrete Bridge Beams Prestressed with Carbon Fiber-Reinforced Polymer (CFRP) Systems, First Edition (2018), covers prestressed concrete beams of normal weight concrete tensioned with CFRP prestressing systems. Section 1 states the scope and limitations and defines material properties for prestressing CFRP, anchorages and couplers, ducts, hold-down points and deviators, and normal weight concrete. Service, fatigue, and strength limit states are established, followed by design considerations that include the effect of imposed deformations and the strut-and-tie model. Design provisions address flexural and axial force effects, shear, and prestressing, including stress limitations, prestress losses, and details for pretensioning and post-tensioning. Durability requirements close the section. The specifications are intended for bridge designers and agencies applying CFRP prestressing to concrete bridge beams.
