摘要

为研究湍流特性对矩形高层建筑风荷载及周围绕流特性的影响，对4种不同地貌条件下9种深宽比的矩形高层建筑进行了风洞测压试验，考察了湍流度与湍流积分尺度对不同深宽比建筑平均、脉动与极值风压，以及横风向气动力谱和流动分离再附特性的影响规律。结果表明，随湍流度增大，分离流更早再附于侧风面上，郊区地貌下再附点出现位置较开阔地貌提前约30%，且分离流下平均风压减小、极值风压增大（均指绝对值），最不利脉动风压与极值出现位置更靠近前缘；随湍流积分尺度减小，迎风面、背风面与侧风面的平均和极值风压均减小，但湍流积分尺度对分离再附流形态及分离流下的风压分布形状影响不大。相对于深宽比更大的情况，湍流特性对深宽比介于1到2的建筑影响更大。

Abstract

In order to study the effects of turbulence characteristics on the wind loads and the flow characteristics for rectangular high-rise buildings

wind tunnel pressure tests were carried out for rectangular buildings with 9 depth-to-width ratios under 4 different terrains. Effects of the turbulence intensity and the integral length scale on the mean

fluctuating and peak pressures

the cross-wind aerodynamic force spectra

and the separation/reattachment flow characteristics for buildings with different depth-to-width ratios were examined. Results show that as the turbulence intensity increases

earlier flow reattachment occurs

and the reattachment point under suburban terrain appears about 30% earlier than that in the open terrain case. Under the separation flow

magnitudes of both the mean and the peak wind pressures decrease

and the most unfavorable fluctuating and peak pressures occur close to the leading edge. As the integral length scale decreases

the mean and the peak pressures on the windward

leeward and side surfaces decrease

but the integral scale has limited effects on the flow patterns for the separation/reattachment flow as well as on the pressure distributions under the separation flow. Among all the depth-to-width ratios studied

turbulence characteristics have greater effects for buildings with depth-to-width ratios between 1 and 2.
