摘　　要：结合低矮房屋的导风研究,对一门式刚架房屋进行了开孔与封闭工况的风洞模型试验,分析了屋面风压的分布规律及开孔对屋面风压分布的影响.试验结果表明:开孔工况的平均风压与极值风压比封闭工况的均有所降低,具有一定的抑风效果.试验结果对低矮房屋基于气动措施的抗风设计具有较大的参考价值.In combination wind leading design research on low -rise buildings, a wind tunnel test is carried out for a model of portal frame building with holes and without holes, the wind pressure distribution and the hole＇s effects is analysed. The tset results show the mean wind pressure and extreme wind pressure of the building with holes is lower than that without holes, the aerodynamic measure opened hole is effect decreasing wind load. The results might be used as references for structural design of wind - resistance.
