Abstract

In order to study the influence of turbulence integral scale on the fluctuating wind pressure and its distribution characteristics on the rectangular windward surface of a high-rise building, rectangular models with 2∶1 and 1∶2 width-depth ratios were put in a wind tunnel to obtain statistical features of wind pressure in turbulent flow fields with different integral scales for comparative analysis, including the mean wind pressure coefficient, root mean square coefficient, correlation coefficient and coherence function, and power spectrum of fluctuating wind pressure. Results are as follows: At the same height of the rectangular model in different turbulence flow fields, the wind pressure power spectrum is dominated by a quasi-steady effect in low-frequency regions, but it increases as the integral scale increases in high-frequency regions. The correlation and coherence of wind pressure increases with the integral scale increasing, and wind pressure is always more correlated than the turbulence flow. However, as the integral scale increases, the correlation width of wind pressure decreases, and the root mean square coefficient of fluctuating wind pressure increases. On the other hand, at different heights of the rectangular model in the same turbulence flow field, the farther away from the stagnation point, the smaller the wind pressure correlation function and coherence function, and the larger the root mean square coefficient of fluctuating wind pressure. In addition, the mean wind pressure coefficient is rarely affected by turbulence integral scale.
