Testing a Prototype Steel-Wood Composite Bridge

A steel-wood composite bridge is presented consisting of longitudinal steel girders and a composite decking of wood laminates, which are laid longitudinally and post-tensioned laterally. Details of the first prototype steel-wood composite bridge constructed in Canada are presented along with the results of field testing. Differences between anticipated values and field test results for the global flexural action of the bridge are discussed. Deflections of the wood deck under concentrated loads are also considered.
