THE MUR RIVER WOODEN BRIDGE, AUSTRIA

This article describes the design and construction of a bridge across the River Mur, to connect the communities of St. Georgen/Murau and St. Lorenzen/Murau in Austria. The chosen design was a wooden bridge with a parabolic three-hinged arch, which functions as the main girder and is also the principal aesthetic element. The bridge's connection elements are made of steel, and there is a concrete deck. The bridge has length 85m and the arch has chord length 45m. A bracing system handles wind and other lateral loads perpendicular to the long axis of the bridge. At the abutment and pier on each side, anchored and reinforced elastomeric bearings are provided, which can resist the tensile forces. All other bearing points, including those for the V- support and the arch, act as pin bearings in the structural system. The structural elements of the bridge were completed in three phases: (1) completion of steel members; (2) lamination of the wood members; (3) component assembly of the wood members. Phases (2) and (3) were concurrent. To prepare for the assembly work, a sufficiently large joining and assembling area had to be provided on both banks of the river.
