World's Aesthetic Foot Bridges

Dr. N. Subramanian, Consulting Engineer, Gaithersburg, MD 20878, USA

Current day footbridges are often built in the urban environment and hence may require collaboration between the architect and the structural engineer. Many types of structural materials such as steel, concrete, prestressed concrete, masonry, timber and fibre-reinforced plastics, and a number of different forms like simple beam, arch, truss, stress-ribbon, cable stayed, cable supported and a combination of these systems could be used efficiently in order to build aesthetic footbridges. A few earlier aesthetic bridges are listed and a few elegant recent footbridges are described. Serviceability problems encountered in a few footbridges and the methods adopted to overcome are also described. An introduction to the current trend of using biomimicry to develop efficient, economic, aesthetic and sustainable footbridges is also provided.
