[摘要]通過風(fēng)洞試驗對某銀行大廈建筑表面的風(fēng)荷載進行了研究,主要分析了典型測點風(fēng)壓系數(shù)隨風(fēng)向角的變化特性,闡述了周邊高層建筑對大廈風(fēng)壓分布的干擾效應(yīng);并對兩種極值風(fēng)壓計算結(jié)果進行了比較和分析,指出由于存在周邊建筑的空氣動力干擾效應(yīng),按統(tǒng)計方法計算的極值風(fēng)壓值比按規(guī)范方法更加合理。

Abstract:A wind-tunnel test of a bank building was performed. Based on the results of the test, the characteristics of the pressure coefficients of typical points on the building′s surface as wind direction are analyzed, and the interference effects of circumjacent buildings on the tall building are investigated. Through comparing the extreme wind pressures obtained by two different methods, i.e., statistical method and code method, it is found that the extreme wind pressures obtained by the statistical method are more reasonable than those by the code method due to the aerodynamic interference from the circumjacent buildings.
Keywords:tall building; wind-tunnel test; interference effect; statistical method; code method
