“…Much research is still aimed at the precise definition of the vertical profiles of the mean wind speed and turbulence in flat open areas, as well as in city centers [ 33 , 34 , 35 , 36 , 37 , 38 ]. In addition to anemometers and lidar, small aircraft systems or quadcopters are used in this type of research.…”

A system designed for making field measurements of wind action on engineering structures is described. The system is composed of sonic anemometers, differential pressure sensors, a barometer, and a thermohygrometer. The focus of this study is to determine the indications of sonic anemometers; to accomplish this goal, wind tunnel tests were performed. The tests did not involve checking the accuracy of the devices themselves, but determining their indications under field measurement conditions where certain unavoidable errors resulting from their installation can appear. The anemometer measurement uncertainty with respect to wind speed and angle was determined. The devices were rotated in a horizontal plane and inclined against and with the mean wind speed direction in a wind tunnel. Different tunnel wind speeds were tested. The results indicate stable device readings at different horizontal plane positions at different wind speeds and a low sensitivity to changes in inclination against the inflow.

“…However, Solari and Piccardo showed that the parameters of the turbulence spectra exhibited vast variability between measurements at different sites (Solari and Piccardo, 2001). The last couple of decades witnessed an impressive number of full-scale measurement campaigns focusing on wind characteristics (Bastos et al, 2018;Cao et al, 2009;Caracoglia and Jones, 2009;Cheynet et al, 2016;Cross et al, 2013;Höbbel et al, 2018;Hui et al, 2009a;Li et al, 2015;Liu et al, 2009;Miyata et al, 2002;Wang et al, 2013). The long-term measurements presented by researchers indicate large randomness in the wind characteristics.…”

In this study, full-scale wind velocity measurements are conducted at eight locations on the Hardanger Bridge girder to investigate the possibility of a probabilistic representation of the turbulence field along the bridge span. Using appropriate assumptions, the two-dimensional turbulence field along the structure is reduced to six turbulence parameters, which are considered as correlated lognormally distributed random variables. The directionality and wind speed dependence of the parameters are demonstrated by means of wind roses and scatter diagrams. Depending on the wind speed and direction, simulations of the turbulence field were carried out using random number generators. The performance of simulated wind fields in capturing the variability and correlation structures of an actual wind field at a site is tested by detailed comparisons with the measurement data. For the sake of illustration, simulations were also performed for the design wind speed of the Hardanger Bridge using the current model and another model from the literature. The resulting probabilistic model is suitable for implementation in reliability-based frameworks and long-term extreme response analysis.
