Mechanical Properties of Double-Layer Riveted Aluminum Roofing Panels with Curved Surfaces

In recent years, aluminum alloy has been increasingly used in building structures, becoming an important construction material for metal structures. Currently, is commonly buildings as beam–column components, profiled roof panels, and door window frames, among other forms. However, there limited research on the mechanical properties of panels with irregular curved surfaces. this study, a full-scale double-layer anisotropic riveted panel was subjected to load test analyze its deformation patterns failure mechanisms. The results indicate that load-bearing capacity meets design requirements. During failure, neither upper nor lower layers enter plastic stage, indicating sufficient safety redundancy. mode observed ductile noticeable weak points component being connections stiffeners. A finite element model established numerical simulation matched well experimental data. Finally, theoretical calculation ultimate derived, providing reference purposes.
