Forced vibration tests have been conducted on the seven-storey timber building Eken in Mariestad inSweden. The main objective is to estimate the building’s dynamic properties from test data. The eigenfrequencies, modeshapes and their scaling are useful to calibrate numerical models. However, the most important outcomes are the estimatesof the modal damping values. The reason is that the damping impacts the acceleration, and thus the serviceability of thebuilding, and at the same time, it is very hard to model damping. So, during the design phase, one must rely on previoustest data (of which very few exist for taller timber buildings) or rule of thumbs. It is therefore important to gain knowledgeabout the damping for timber buildings in order to enable good designs of future and taller timber buildings. The test datashows that the modal damping is roughly equal to 2% of the critical viscous ones for the eigenmodes extracted. The testcampaign on Eken is made as a part of the project Dyna-TTB in which vibrational tests have been performed on eighthigh-rise timber buildings, in Europe, of which Eken is one.
