Investigation of Carbon Fiber Composite Cables (CFCC) in Prestressed Concrete Piles, Summary Report.

摘要

This study demonstrated that the performance of piles prestressed with CFCC strands is comparable to those prestressed with steel. Researchers concluded that CFCC-prestressed concrete piles can be a good alternative to conventional concrete piles with steel prestressing, particularly for bridge foundations in corrosive environments. Although constructing prestressed concrete piles with CFCC strands instead of steel initially costs more, the use of CFCC can result in bridges that require less maintenance and last much longer, thus reducing the long-term cost of bridges.
