摘要
国内金属屋面抗风性能设计方法相对还不成熟。本研究通过试验手段,对两种不同厚度的直立锁边镀铝锌钢板在不同檩条间距下的抗风揭试验数据进行分析,得出在屋面板本身强度较高比强度较低时,缩小檩条间距对屋面板系统的抗风等级提升效果更加显著的结论。
The domestic design approach of wind resistant performance of metal roof is relatively immature.Through experimental means,the article analyzes the wind uplift resistance test data of standing seam Al-Zn alloy coated steel sheet of two different thickness at different spaces between purlins,and it reaches a conclusion that when the strength of the roof plate itself is higher,lessening the gaps between purlins has more obvious effect on improvement of wind resistance of the roof plate system.
