国内外在计算高层建筑的渗风时,都引入了风压和热压系数的概念来计算外墙渗风压差。但采用的数据一般限于经验的或实测的结果,缺乏对这两个系数本质的阐明及定量的分析。本文通过理论分析和计算机模拟实验,就如何合理地选取风压、热压系数的问题,进行了研究,以弥补这方面的不足。 When calculating the infiltration of high-rise buildings at home and abroad, the concept of wind pressure and thermal pressure coefficient was introduced to calculate the differential pressure of the external wall seepage. However, the data used are generally limited to empirical or measured results, lacking the elucidation and quantitative analysis of the nature of these two coefficients. In this paper, through theoretical analysis and computer simulation experiments, we have conducted research on how to reasonably select the wind pressure and thermal pressure coefficients to make up for this deficiency.
