Due to their light-weight nature, multi-storey timber buildings are susceptible to wind-induced vibration, which can cause discomfort to the occupants. Therefore, vibration serviceability is often one of the key criteria in the design of multi-storey timber buildings. In this article, we calculate the expected accelerations of wind-induced vibration for 10 timber and hybrid timber buildings with heights between 22 m and 74 m, for which we have obtained data on dimensions, mass and modal properties. The accelerations were calculated according to SIST EN 1991-1-4:2005 and evaluated according to ISO 10137. The parametric analysis showed that the location of the building has the greatest influence on the expected wind-induced accelerations. Among the parameters of the building shape, the radius of the rounded edges proved to have the greatest impact. It was also found that increasing the stiffness of the building contributes better to improving the comfort criterion for lower buildings, while adding mass is better for taller buildings. The analysis also included the current tallest timber building in the world and showed the potential for even taller timber buildings in the future.
