摘　　要：对于外型不规则的高耸建筑结构,特别是存在相邻建筑物干扰时,其体型系数值将会发生显著变化,导致所得到的风荷载误差很大。为了研究这一问题,在北京大学环境学院国家重点实验室2号环境风洞中,对缩尺比为1∶300的英利大厦模型进行了风洞试验,获得了作用于该建筑物上的静、动态风压,通过对试验结果进行分析、计算,直接求出了该建筑物的体型系数值。Considering the complication of the coefficient of wind-induced vibration for tall buildings, the scale 1：300 model test of Ying Li Building is completed in the second wind tunnel of Beijing University. Based on the calculation and analysis of the test results, the static and dynamic wind pressure acting on the building can be obtained and the value of the coefficient of wind-induced vibration for this tall building canbe solved directly, thus a new way is laid for the research of complicated tall buildings.
