dc.description.abstractDue to corrosion of steel reinforcement in concrete structures, the search of other material compositions and design methods has been carried out throughout the world. Glass Fibre Reinforced Polymer (GFRP) is one type of material that has been tested and evaluated as a reliable alternative. This thesis has introduced this relatively new material emphasizing historical development through a «state of the art» presentation. Also the different aspects of why, when and where to use this material as well as different design approaches have been presented. Designing a bridge deck from an already existing footbridge was then carried out using design approaches given in the Canadian standard CSA S806. Calculating loads acting on the bridge deck and the combination of these was done according to Eurocodes and custom guidelines for Statens Vegvesen. Both hand calculations and a numerical computer program were used to retrieve the loads. The analysis of all the load combinations on the bridge deck was done using CSI Bridge, which is an analysis and design software for the engineering of bridge systems. The bridge deck was divided into a beam and a side slab because of its cross sectional geometry and designed for both ultimate limit state and serviceability limit state. Furthermore, the costs related to the amount of materials needed to achieve required resistance were evaluated. Initial costs were calculated for both steel and GFRP and the predicted deviance was verified by the results. Also life cycle costs were discussed, but due to lack of exact data it was here only made a rough estimate regarding the annual costs considering maintenance work for repairing corrosion damages. It was concluded based on retrieved results that the use of GFRP as reinforcement instead of steel can be implemented as a liable and sustainable alternative to steel reinforcement. On the other hand, more attention should be given to the design methods and application of these. Also, the difference in initial costs may be a reason for many contractors not to choose GFRP as their solution.nb_NO
