［摘要］通过风洞试验对某银行大厦建筑表面的风荷载进行了研究，主要分析了典型测点风压系数随风向角的变化特性，阐述了周边高层建筑对大厦风压分布的干扰效应；并对两种极值风压计算结果进行了比较和分析，指出由于存在周边建筑的空气动力干扰效应，按统计方法计算的极值风压值比按规范方法更加合理。

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
