| 摘 要： | 以西安地区一实际高层建筑为例,研究了在热压和风压共同作用下自然通风对高层建筑楼梯间空气流动状况的影响,以及在热压单独作用下楼梯间的烟囱效应。通过对不同天气情况下楼梯间门洞风速和温度的实测,测出了烟囱效应现象并了解到了天气状况对楼梯间中和面的位置和楼梯间内空气流动方向的影响比较大。

| Abstract: | The article takes one actual high-rise building in Xi'an as an example,studying to the influence of natural ventilation by the combined effects of buoyancy and wind,to the air flows in the stairs of high-rise building,and also studying to the chimney effect under the buoyancy alone in the stairs.Through measuring temperatures and wind speeds in the stairs under different weather,it is shown the chimney effect phenomenon and understand that weather condition influence the neutral plane and the air flows direction greatly inside the stairs. |
