Design of Concrete Bridge Beams Prestressed with CFRP Systems
Carbon fiber reinforced polymer (CFRP) is becoming a recognized alternative to traditional
construction materials in a wide range of civil engineering applications. An example of
such applications is the use of CFRP cables or bars as prestressing tendons for concrete bridge
girders, especially in aggressive environments where steel prestressing strands are susceptible
to corrosion.
Despite their promise, CFRP prestressing tendons have not frequently been used
for bridge construction in the United States; their use has been hampered by the lack of
recognized design specifications.
NCHRP (National Cooperative Highway Research Program) Research Report 907: Design of Concrete Bridge Beams Prestressed with CFRP Systems proposes guidelines and presents research findings that are expected to
advance and facilitate the use of CFRP systems in bridge applications. In addition,
five design examples that illustrate the step-by-step
use of the proposed guide specifications are provided.
