Light Road Gluelam Bridge at Yarrawonga, Australia

This paper describes the structural design of a forty metre span, glue-laminated, three-pinned arch, light road bridge and footbridge for use at a holiday resort in Yarrawonga in the State of Victoria, Australia. Three-pinned arch, glue-laminated pine bridges had been previously designed for pedestrians only and this was considered a first in design for road passenger vehicles. As the resort management assured the designers that trucks and highway vehicles would be excluded from the bridge site and had alternative access, a unique loading set of resort vehicles and trailers was established. The paper describes the design of the abutments and superstructure and the use of computer analysis. Unfortunately, the project did not proceed and the bridge has not been constructed.
