Exciting Mechanisms of Rain-Wind-Induced Vibrations

Structural Engineering International, 1998
Dangerous rain-wind-induced vibrations can occur in cables of cable-stayed bridges and in the steel hangers of large arch bridges with circular cross sections and low values of structural damping. Serviceability and safety of the structure may be reduced.

Conversion of wind-induced vibrations into electricity

2014 IEEE 36th International Telecommunications Energy Conference (INTELEC), 2014
The recently growing concern to reduce the energy from non-renewable sources encourages the development of new energy harvesting methods. In case of unattended remote telecom equipment, it should be advantageous to obtain energy from the wind while no rotation is applied.

Wind-induced vibrations monitoring with satellite navigation

IABSE Congress Reports, 2016
<p>A Global Navigation Satellite System (GNSS) has been deployed on the Lysefjord Bridge in Norway, to measure the static and dynamic displacement of the deck. One objective is to evaluate the systems capability to monitor accurately wind-induced vibrations in high-latitudes and mountainous terrain.

Wind-induced vibrations of tall buildings

2008
The new generation of tall buildings is higher and more slender than the buildings built before. Additionally, increased use is made of high-strength materials that however do not have a higher stiffness than the conventional materials. Both aspects increase the sensitivity of tall buildings to dynamic behaviour.

Structural damper for eliminating wind induced vibrations

The Journal of the Acoustical Society of America, 1983
A damping assembly for reducing wind-induced vibrations in elongated strures comprises a plurality of damping tubes suspended within the structure in end-to-end relationship so that the end portions of the damping tubes are disposed in abutting relationship with the inner surface of the structure.

Wind-Induced Vibration Analysis in Time Domain

2011 Fourth International Conference on Information and Computing, 2011
Based on harmonic superposition method (WAWS method) under the situation of multiple fluctuating wind speed, the spatial correlation of multi-point and Simiu spectrum were considered. Meanwhile decimation in time Fast Fourier Transform method (DIT-FFT method) was carried on optimizing the speed of wind. Then the fluctuating wind speed long direction of

Damping Measures to Control Wind-Induced Vibrations

1994
The possibilities of passive and active control of wind-induced vibrations of structures in civil engineering are presented. The concept of control by means of mechanical and aerodynamic devices is discussed using results of theoretical and experimentel investigations (model tests and full scale examinations).
