The construction sector is one of the largest sources of greenhouse gas emissions in the world today and are in great need of change and improvement. A building material that if handled properly, can contribute to reducing emissions is wood as it is the only renewable building material we have available. Wood has been the dominating material in bridge construction throughout history, until the last 200 years which have been characterized by concrete- and steel constructions. The relatively (relative?) new glulam can often compete with steel and concrete an make wood an attractive choice of material for example bridge constructions. In Karlstad a bridge of 280m for pedestrian traffic is planned to run over Klarälven and this bridge is the basis of our thesis. The bridge extends from Råtorp to Färjestad and is planned to have a frame of steel. The goal of this thesis is to design the same bridge, according to the eurocodes, with a supporting glulam frame using the computer-aided design software Robot Structural Analysis and the CAD-software Revit Structure. The bridge is sized for deadloads, snowload, windload and trafficloads both moving and static. The results shows that computer-aided design software can be used to great effect when sizing wooden bridges with glulam as a supporting frame, for example by calculating the results of all the possible positions of moving loads in an instant. It also shows that it is fully possible to construct a 280m long bridge made out of wood.
