Development of a modular footbridge system with pre-tensioned CFRP reinforcement
Pre-design and experimental investigations
Road and pedestrian bridges are commonly built as cast-in-situ, prestressed reinforced concrete structures, but this method is both expensive and time-consuming. The installed reinforcing and prestressing steel requires a high concrete cover to ensure corrosion protection, which results in massive members. Nonetheless, it is often impossible to prevent corrosion damage to the steel reinforcement, such as caused by penetration of chlorides from de-icing salt into the concrete. The associated loss of bearing capacity as well as visual or aesthetic deficiencies require expensive, labor-intensive...
