Abstrakt:

A common problem of concrete bridges are corrosion damages of the steel reinforcement. The related loss of capacity as well as visual effects 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 non-corrosive carbon fiber reinforced polymer (CFRP) reinforcement is suitable for building slender constructions which are durable and long- lasting. To enhance the durability and reduce costs, high strength concrete (HSC) with high density is applied. Hence, no additional surface is required. The modular construction method allows for fast assembly and disassembly of the footbridge. This paper presents the dimensioning and flexural pre-design of the modular footbridge system.
