| Abstract: |
The paper describes the new superstructure for Kagraner Steg pedestrian bridge in Vienna, Austria. The original one, made of timber in 1991, must be replaced due to exploitational problems and frequent traffic disturbances during repair measures. The existing foundations must be used for the new superstructure. Different material options were compared in the concept design phase. Finally, glass fibre reinforced polymer (GFRP) was chosen due to its low weight, high strength, and minimal maintenance cost. To justify its initial higher costs, a life-cycle costs analysis has been performed. The results of the analysis compared with conventional carbon steel alternative solution, are presented. In addition, the article reviews the challenges met during the design of the new GFRP superstructure of Kagraner Steg. |
