Project: Durable timber bridges

Many new bridges are needed due to altered use and bad conditions beyond repair. Most of these bridges have quite small spans, in the range 10 to 120 m, crossing roads and rivers. Bridges are vital components of the transport infrastructure, and the closing time in case of renovation is critical. timber bridges are well suited for this span range; they offer quick installation on site and can utilize existing foundation due to low weight. the research project aims to improve the general standing and applicability of wood as a structural material in environmentally friendly bridges. the overall objective of the project is to develop durable timber bridges with a given estimated technical lifetime. the scientific and technological objectives cover; development of a performance based service life design model for timber bridges, validated computer models for prediction of moisture distribution and moisture traps and new design concepts for durable timber bridges with spans up to 150 m.
