The technique for building with stress-laminated-timber bridge decks is well established and is becoming more popular. Timber should be a natural choice of material when constructing new short to medium span bridges at a lower cost, with faster production and good sustainability. More knowledge of mechanical behaviour, both in serviceability and ultimate limit state, is needed to ensure further development of timber bridges. The overall aim is to establish new knowledge about mechanical behaviour of stress laminated timber for a more efficient design and modelling. The mechanical behaviour of timber bridges can be efficiently studied by combining strategies for both experiments and design models. With obtained research results as basis, new design methods can be suggested. Distribution of knowledge and overall timber competence is also an aim for this project. This is to ensure efficient timber bridge design and construction and finally enhance the competitiveness of timber bridges.
The project is carried out at the Division of Structural Engineering in the research group Steel and Timber Strucutures.
