Abstract
Conventional design methodologies for wind loads frequently depend on static analyses, which may inadequately represent the dynamic behavior of certain structures, such as tall buildings or wind turbines.In such instances, time-domain analysis is more suitable for accurately capturing the wind-induced effects.Time-dependent wind loads for design purposes are typically derived from wind tunnel tests. However, conducting such tests during the preliminary design stages is often impractical due to cost constraints and the potential for iterative design changes.
This study proposes a methodology for generating multivariate wind speed fields to be used in the calculation of time-dependent wind loads on structures and in applications such as energy production.The proposed methodology is based on the modeling of the spectrum of atmospheric surface-layer turbulence according to basic wind velocities. It enables the simulation of one-, two-, or three-dimensional fields with one, two, or three components of wind velocity fluctuations (u, v, w). The simulation of these velocity fields is conducted with the models characterized as gaussian random processes dependent on the parameters 𝑡 and x position within a finite spatial domain. As a demonstrative application, this study presents a regular 2D vertical grid oriented perpendicularly to the flow, incorporating the longitudinal mean wind velocity and the longitudinal, lateral, and vertical atmospheric turbulence components. This approach can offer a cost-effective and versatile solution for wind analysis, enhancing preliminary design processes and broadening applications in structural and energy-related fields.
