摘　　要：通过不同边界层条件下的风洞试验,对典型高层建筑表面风压分布规律进行了对比研究。获得了不同风场下建筑幕墙表面的平均风压系数和峰值风压系数,评估了风场的改变对各种无量纲风压系数的影响。测试的结果可以为高层建筑幕墙设计提供依据,同时,也为其它高层建筑的抗风设计和风洞试验提供技术参考。The distributions of wind-induced pressure on a tall building were evaluated by a wind tunnel test in two boundary layers. This paper presents some selected results of the mean pressure coefficients and peak pressure coeffi- cients on the tall building based on the analysis of the data obtained in the wind tunnel test. In addition, further studies were conducted to investigate how the pressure coefficients of the tall building are influenced by the variations of boundary layers. The outcomes of this study are expected to be useful to determine the wind loads on curtain walls of the tall build- ing in the design stage, and also provide guidelines for the design and wind tunnel tests for other similar structures in the future.
