“…One notable use of CFRP reinforcement (in the form of Carbon Fibre Composite Cables CFCC) in concrete, is the deck of the Herning Footbridge in Denmark (Christofferson et al, 1999). The bridge has two 40 m spans supported by sixteen CFRP cable stays from a steel pylon and six unbonded post-tensioned CFRP tendons in the concrete deck.…”

“…The CFRP reinforced section of deck was designed to be over-reinforced and additional CFRP stirrups were placed in the compression zone to provide confinement to the concrete. Significant compressive strains and rotations would therefore be expected prior to failure due to concrete crushing [35].…”

Recent developments in the use of fibre‐reinforced polymers (FRPs) in reinforced and prestressed concrete applications are reviewed. The influence of FRP material properties on the design of concrete structures is considered and applications are discussed in conjunction with the structural function of the FRP reinforcement. The review includes examples of the practical implementation of the technology and addresses important durability issues. A number of future considerations/research needs are identified and the requirement for the provision of standard, sustainable and cost‐effective FRP solutions is highlighted. It is concluded that although there have been significant advances in our knowledge of the behaviour of FRP‐concrete structures, the timeframe in which FRPs will no longer be considered as new materials remains ambiguous.

“…The related loss of capacity as well as visual damages require expensive and elaborate refurbishment or even reconstruction. To solve these problems, the application of noncorrosive FRP reinforcement in footbridge constructions has been investigated over the last years by various researchers to provide the basis for sustainable and long‐lasting footbridges with a high load capacity.…”

A common problem of concrete footbridges are corrosion damages of the steel reinforcement. The related loss of capacity as well as visual damages often require expensive and elaborate refurbishment or even reconstruction. To overcome these drawbacks, a modular footbridge system without steel reinforcement is developed. The application of noncorrosive carbon fiber reinforced polymer (CFRP) reinforcement is suitable for building slender constructions, which are durable and long‐lasting. For the elements of the modular bridge system CFRP reinforcement is applied as mesh fabrics and pretensioned tendons. To enhance the durability and reduce costs, high strength concrete (HSC) with a high density is applied. Another advantage of the high density is that no additional surface is required. The modular construction method allows for fast assembly and disassembly of the footbridge. In this paper, the dimensioning and flexural design of the modular footbridge system are presented. In a first step, the requirements regarding cross sections, spans, and level of prestressing are defined based on natural conditions and applied loads. The results are analyzed considering the realization of a modular construction. In a second step, the flexural design of the pretensioned footbridge is presented. In this context, a flexural design model for beams pretensioned with CFRP tendons based on Eurocode 2 is developed.
