Abstract [en]

Tall timber buildings are built around the world and the development is moving forward. Tall timber buildings are sensitive to wind-induced vibration and can cause discomfort for humans. In this report is the results from a dynamic analysis preformed on a cross-laminated buildings system presented. Size and placement of openings and floor plans have been investigated using finite element analysis and dynamic modal analyses. The results show that asymmetric placement of openings and asymmetric floor plans may affect the dynamic behaviour of tall timber buildings. Asymmetry can cause modes with a tendency to rotate and even diagonal modes. Timber buildings may have problem to fulfil the comfort criteria already at a slenderness of 1.5-2.1.
