The Design of Network Arches

Network arches are bowstring arch bridges with inclined hangers which have multiple intersections. These bridges are very light and economical, which is illustrated by two such bridges built in Norway. A diagram (Fig 8) gives the steel quantities for various spans of network arches with two sets of hangers. Arches and hangers for these bridges can be erected with a light temporary lower chord which carries the formwork for casting the concrete deck. Per Tveit
