【摘要】 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.更多还原

【Abstract】 The results and measuring method of pressure difference distribution for a four-story domitory building are given in the paper. The measurements show that the pressure differences along the same side at certain hight are similar, the thermal pressure is dominant and the wind pressure is small, compared with thermal pressure.In the noutheast China, the thermal pressure is the primary factor for calculating the air leakage heat loads of urban multistory buildings.更多还原
