Abstract
This paper describes a project that aims at evaluating the dynamic properties of tall timber structures under wind-induced vibration in serviceability level from a series of onsite measurements on existing multi-storey timber buildings and timber towers. Ambient vibration measurement was carried out on nine timber towers and three tall timber buildings to derive dynamic parameters including natural frequencies, damping ratios, and mode shapes. The results were analysed by time and frequency domain approach. The factors that influence the dynamic parameters, such as construction type, height, and vibration amplitudes, are discussed. The outcomes of this paper are useful for engineers to evaluate the dynamic parameters in the design of tall timber structures.
