本文报告了对一栋四层宿舍楼压差分布的测定方法及结果.压差测定包括周边压差分布及中部垂向压差分布,测定表明在任一侧面同一水平线上的压差可认为是均匀的.在此基础上给出了压差分布的回归关联式.实测表明,热压在该建筑中占主导地位,风压的影响较小.建议东北地区,计算市内多层建筑渗风负荷时以热压为主.
This paper reports on the measurement method and results of the pressure difference distribution of a four-story dormitory building. The differential pressure measurement includes the distribution of the peripheral pressure difference and the vertical vertical pressure difference. The measurement shows that the pressure difference on the same horizontal line on any side can be considered as uniform. Based on this, the regression correlation formula of pressure drop distribution is given. The actual measurement shows that the hot pressure is dominant in this building, and the influence of wind pressure is less. It is recommended that the northeastern region should calculate the infiltration load of multi-storey buildings in the city. Hot pressure is the main factor.
