摘要: 对大量应用于屋面围护系统中的角驰Ⅲ型屋面板,为确认其理论、实际抗风揭能力以及采取加固措施后的抗风性能提升程度,对该板型的构造特点、抗风能力进行了分析,继而以实际工程项目中的屋面围护系统为例,对其理论抗风能力进行了验算,并根据系统构件布置对其抗风揭试验标准试件的实际抗风承载力进行了抗风揭试验研究。通过对原型系统抗风试验承载力低的原因进行分析后,提出了有针对性的加固措施,并对采取加固措施后的系统进行了抗风揭试验验证。试验结果表明,加固后系统抗风揭能力相较于原型板系统有较大提升。Abstract: For the YX51-380-760 corrugated roof plate which has been widely applied in the metal roof, in order to confirm its theoretical and actual wind-uplift resistance and the improvement degree of wind resistance after reinforcement,the paper analyzed the structural feature and wind-uplift resistance capacity of this type of plate. then the work of checking the theoretical wind-uplift resistance capacity was conducted on an actual project, and the reasons for the low bearing capacity of the prototype system in the wind resistance test were amalysed. The targeted reinforcement measures were put forward, and the wind resistance test was carried out to verify the system after the reinforcement measures were taken. The test results showed that the wind-uplift resistance of the reinforced system was greatly improved compared with the prototype plate system.
