Gust-induced response of a high-rise tower: comparison of in-situ measurements with code provisions
conference paper
This paper analyses gust-induced vibrations in a high-rise residential tower, comparing in-situ measurements with predictions based on current codes. Extensive data from the New Orleans Tower in Rotterdam, equipped with accelerometers and anemometers, is evaluated against predictions from the Eurocode and wind tunnel tests. The findings reveal discrepancies between measured and predicted accelerations, indicating that codes may underestimate the impact of neighbouring structures and wind directionality. Detailed assessments of aerodynamic force coefficients and structural dynamics were conducted to refine prediction models. The study highlights the need for more accurate urban wind modelling and better consideration of building-specific factors in structural design codes, emphasizing the integration of detailed in-situ data and advanced computational methods for reliable wind-induced vibration predictions in high-rise buildings.
