| 摘 要： | 应用风洞实验方法,研究了中央电视塔塔楼表面风荷载与塔楼进排风口的风环境,后者考虑了进排风的模拟并且做了为改善进排风口的风环境对局部结构进行变动的实验研究。实验结果提供了塔楼表面的平均和脉动风压系数分布以及进排风的风环境特性,并对局部结构的改进提出了建议。

| Abstract: | The wind loads on the CCTV tower building and the en-vironment neaby the vents of the air-conditioners in the building wastested by means of wind tunnel modelling.It was considered to simu-late the flow caused by pumping and exhausting.Some tests to improvethe wind environment of the vents was conducted too.The experimen-tal results give mean and fluctuating pressure distributions on the sur-face of the building and the characteristics of wind environment of thevents.Some suggestions on changing a part of the structure of the TVtower building was given also. |
