Experimental investigation on the behavior of a tall and slender building placed in a turbulent boundary layer

Predictions on the dynamic behaviour of an aeroelastic model of a television tower in the boundary layer wind tunnel

“…Moreover, during the calibration process the property of internal similitude in the wind tunnel was observed. This means that for a certain height of the variable roughness, the non-dimensional mean wind speed profile and the turbulence intensity profile are the almost same (except for a small area near the ground), with respect to the frequency shift of the axial fan [4][5]. This property is obvious from Fig.…”

“…( ) In order to calibrate the wind tunnel three different roughness heights were considered, namely 0 mm, 50 mm and 100 mm. Superposing experimental measured values [4][5] over the above-mentioned Eurocode curves the best match was found for the roughness height of 100mm. The profiles for the mean wind speed and turbulence intensity are plotted in Fig.…”

“…In the last two decades, there have been numerous studies on the behaviour of structures in the boundary layer wind tunnel. [3][4][5][6][7][8][9][10][11][12][13][14][15][16] can be mentioned among the works of great importance in this area.…”

“…1. The aeroelastic model of the television tower, scale 1:500 (left side and middle side) and the Gondola of the television tower (right side) [4][5].…”

“…Also, depending on the type's terrain roughness described in Eurocode, Bucharest is placed in the 4 th category i.e. an area which at least 15% of the surface is covered with buildings and their average height exceeds 15 m. In this way, we could get the characteristic curves of this site, in terms of mean wind speed profile and turbulence intensity profile [4][5].…”
