Wind Induced Ground Motion
Wind noise is a problem in seismic surveys and can mask the seismic signals at low frequency. Development of practical solutions to this problem must be based on a good understanding of the mechanism of the wind-ground coupling. This thesis investigates the driving pressure and shear stress …

Wind-induced dynamic response of bridges
Wind loading has long played a significant role in bridge design. Some spectacular failures, such as the Tay Bridge (Scotland, 1879), or the Tacoma Narrows Bridge (Washington State, 1940) acted as a painful reminder to engineers in case they had forgotten the importance of wind loading. Today, a …

Wind-Induced Exchange in Semi-Enclosed Basins
<p>The wind-induced circulation over laterally varying bathymetry was investigated in homogeneous and in stratified systems using the three-dimensional Regional Ocean Model (ROMS). For homogeneous systems, the focus was to describe the influence of the earth's rotation on the lateral distribution …

Wind-induced dynamic responses of structures with outrigger systems
… its number, locations and rotational stiffness. Wind-induced along-wind and across-wind responses of structures with and without outrigger system were analyzed, compared and discussed. It was found that the outrigger system can effectively decrease the along-wind responses (peak displacements and …

Reduction of wind induced microphone noise using singular spectrum analysis technique
Wind induced noise in microphone signals is one of the major concerns of outdoor acoustic signal acquisition. It affects many field measurement and audio recording scenarios. Filtering such noise is known to be difficult due to its broadband and time varying nature. This thesis is presented in the …

Wind-induced interference effects on buildings : integrating experimental and computerized approaches
Wind-induced interference effects are caused by the presence of adjacent structures, resulting in an increase or a decrease in the wind loads on a building depending mainly on the geometry and arrangement of these buildings, their orientation with respect to the direction of wind and upstream …
