Title: DESIGNING TIMBER BRIDGES FOR LONG LIFE
Accession Number: 00459726
Record Type: Component
Availability: Find a library where document is available Abstract: Wood is a marvelously adaptable structural building material. When treated with a compatible preservative to prevent early decay deterioration, it is an economical and practical structural material for many short-span bridges (spans in the range of 15 to 60 ft). Timber's inertness to deicing chemicals, as well as some new design developments, such as glued-laminated deck panels and prestressed laminated decks, make it more attractive than ever for use in highway structures. Important factors in assuring long, useful lives for timber bridges include designing to avoid water-trapping details, use of effective and compatible preservative treatment, and following a systematic inspection and maintenance program. Attention to these factors will provide a lifespan that is competitive with other structural materials, such as steel and concrete, and will, in most cases, dramatically increase the useful life of timber bridges.
