Footbridges

Footbridges’ design is presented as a special case of bridge engineering and as an opportunity for close collaboration between architects and engineers. The range of structural form and materials used in construction is wide and the parameters employed to generate a design and then assess its success are discussed. Footbridge types are loosely classified and the characteristics of the most common components examined. The principles of setting out are described and extended to considerations of context. Detailing and maintenance regimes are identified as critical concerns. The importance of finishes is highlighted. Structural dimensions and aesthetic principles are treated together. It is concluded that future developments will include innovation in materials, construction processes and most importantly design techniques and the critical analysis of completed works. Ten case studies provide specific examples of general principles.
