Short Flexible Suspension Bridges for Heavy Trucks
Temporary flexible suspension bridges often needed during construction of Swedish hydro-electric power plants to carry heavy trucks are described. A method of analysis (by “Green's Matrix”) for bridges with a finite hanger spacing is summarized. Large movements of the suspended span and large inclinations of the middle hangers may appear when traffic is on one-half of the span. Design details of shoes, expansion joints, hanger connections, and saddles that are influenced by such movements, are discussed. Some details of the erection of such bridges are described. Their performance under heavy traffic and the way in which weaknesses were corrected is reported.
