Abstract : wind tunnel experiments were carried out to investigate the influence of wind direction on the wind pressure of proximite buildings. mean and fluctuating pressure coefficients on a high building, at sixteen different wind incidences and with one and two interfering buildings, were measured in the tests. this paper presents the characteristics of wind pressure on the building, which varies with the incident wind angle and with the numbers of adjacent buildins. due to the variation of wind angle and the interference effects, the complex feature of pressure distributions can be found on the downstream building surfaces for building group arrangement at certain angle of wind attack. some area of the interfered building for such configuration, in comparison with one single building ' s, may undergo very strong positive or negative pressures
文摘:通過風洞實驗研究了風向對兩個和三個鄰近建築風壓分佈的影響特性.實驗結果給出了在不同風向角下，作用於受擾建築上的平均和脈動風壓系數.當受擾建築處于下游位置時，建築之間的干擾效應主要表現為遮擋影響，建築物上的總體風壓系數不是很大，但在建築物表面上有時會產生局部較大的負壓系數.另外，在某些風向角下由於受到上游分離氣流的影響，在下游建築的局部表面又會出現較大正壓.這些結果可供建築布置和結構設計時參考 -
