Monitoring the behavior of a high-rise building under wind loads

To assess the ecological risk parameters, instrumental measurements of the intrinsic characteristics and vibration amplitudes of the 34-storey high-rise building “Transport Tower” in the city of Nur-Sultan were performed under wind loads. The observation interval is two days. The measurements were carried out using a digital instrumentation system. Acceleration values measured at the top of the building over two days of monitoring. An excess of the comfortable level of 8 cm/s² was detected. When measuring the values of the kinematic characteristics, an acceleration value of 9.23 cm/s² was recorded. The experimental and theoretical periods of vibration of the building in the first and second modes of vibration are determined. To reduce the level of accelerations under wind loads, it is suggested to use vibration dampers or viscous vibration dampers.
