Portable Timber Bridge Systems for Forest Roads
Interest in portable bridge systems has increased in the US due to heightened awareness for reducing environmental impacts and costs associated with road stream crossings. This paper presents case studies of portable bridges constructd with longitudinal glued-laminated timber decks and it discusses appropriate levels of strength design criteria for portable bridges. Specific emphasis is given to quantifying the effects of dynamic loads on portable bridge design.
