Quantification of wind-induced coupled vibrations of a high-rise structure
conference paper
Vibration comfort is an important aspect of the design of high-rise structures. The prediction of wind-induced vibration amplitudes is based on a combination of models for structural components and wind load mechanisms. Estimated values need to be compared to comfort criteria. Data of long-term vibration monitoring on a high-rise building are
presented here, focusing on the effect of coupled motion and the influence of neighbouring high-rise structures on the observed responses. Confidence levels are computed as elliptical shapes to assess the effect of coupled motion and study the in-wind and cross-wind responses. The analysis of nine years of data provides a statistical overview of dependencies to wind conditions and detailed insights into the shape of motion within single storm events. Based on the measured data, a significant influence of neighbouring structures has been determined and quantified.
