Design and Construction of a Timber Bridge (National Timber Bridge Design Competition)

Design and Construction of a Timber Bridge (National Timber Bridge Design Competition)

Students: Charles Bado, Kevin Donahue, Ted Forgit, Tom Krajewski, Anna Novey, Matt Peterson, Chris Phelps Faculty Sponsor: Peggi Clouston, BMATWT, NRC Project Type: Independent Study Year: 2003 Introduction: The purpose of this project was to conceptually design, construct and non-destructively test a full-size pedestrian timber bridge. The guidelines for construction are those set out by the National Timber Bridge Design Competition which is an annual event sponsored by the United States Department of Agriculture (USDA) and the United States Forest Products Service. The competition is open to universities across the US and Canada for student chapters of the American Society of Civil Engineering (ASCE) as well as the Forest Products Society (FPS). Aim of Project: The aim of the project was to construct a fully functional bridge (treated to AWPA standards for "above ground use") which has: Minimal overall bridge deflection Minimal deck deflection Minimal weight A maximum of 25% non-wood content by weight The bridge was designed and built with the intent that it would be used in a local trail or...

Register for the 2007 Wood Structures Symposium

Building with wood is building for the future Contemporary wood architecture demonstrates ingenuity and new direction. In the quest for sustainable building materials, life-cycle analysis studies consistently show wood as having top environmental benefits: it is energy efficient in production and operation; it absorbs and stores the greenhouse gas carbon dioxide; and it is renewable, recyclable, and sustainable. As a result, wood is becoming a material of choice in award winning environmentally green structures as well as a prominent building material used in showcase projects at world expositions. This two-day meeting will discuss and illustrate the latest innovations in wood architecture, engineering and construction. Topics include: contemporary wood architecture world-wide, wood and the environment, technological advances in green buildings, digital fabrication with wood and detailing of engineered wood products. A full day workshop by the American Wood Council on...
