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。 Through the wind tunnel tests under different boundary conditions, the wind pressure distribution of typical high-rise buildings was compared. The average wind pressure coefficient and peak wind pressure coefficient of building curtain wall under different wind fields were obtained, and the influence of wind field changes on various dimensionless wind pressure coefficients was evaluated. The test results can provide the basis for the design of high-rise building curtain wall, and also provide technical reference for the wind-resistant design and wind tunnel test of other high-rise buildings.
