In order to study the infl uence of stiff eners on the wind resistance performance of the aluminum panel curtain wall unit (APCU), two APCU specimens with diff erent structures were designed and fabricated. The deformations under positive and negative wind loads were studied. The defl ection, stress, and mode were analyzed by fi nite element software. The results indicate that the stiff eners and the aluminum panels work well with each other under positive and negative wind pressure. Adequately designed stiff eners can eff ectively improve the wind resistance of the APCU, reduce the deformation of the aluminum curtain wall, and make the stress distribution uniform. The shedding of aluminum welding nails has a signifi cant impact on the overall wind resistance performance of the component. The aluminum panels and the stiff eners reduce the wind resistance performance of the APCU when the aluminum panels and stiff eners are not fi rmly connected. The modal analysis points out the weak point of the specimens. The fi nite element calculations and analysis results are consistent with the actual measurement results. The research results can guide engineering applications. The research in this paper can provide guidance for wind resistance of aluminum plate, defl ection deformation of stiff ening rib, failure of aluminum plate under wind pressure and engineering research of aluminum curtain wall system under wind load.
