ANALYSIS AND EXPERIMENTAL RESEARCH ON WIND-UPLIFT RESISTANCE OF YX51-380-760 CORRUGATED ROOF PLATE APPLIED IN ENCLOSURE SYSTEM BEFORE AND AFTER REINFORCEMENT

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.
