What are the common wind resistance considerations for membrane structure parking sheds? Today, the editor briefly introduces the design methods for wind resistance in membrane structure design.
To clarify the mechanism of灾变 in the品格dynamic of clear membrane structural parking canopies, research progress has been discussed from aspects such as on-site measurements, wind tunnel tests of aerodynamic and elastic models, and fluid-structure coupling numerical simulations. The study indicates that due to constraints from on-site measurement equipment, similar theories of aerodynamic and elastic model tests, and fluid-structure coupling simulation methods, there is still relatively little research on the observation and simulation of fluid-structure coupling phenomena in practical engineering.
In the field of fluid-structure interaction oscillation mechanisms, it is commonly believed that aero-elastic instability is related to vortices formed near the surface of the structure, which is manifested as a significant decrease in the structure's total damping ratio. However, existing research findings often rely on observations of oscillations in simplified membrane structures in approximately uniform flow fields, which differ significantly from practical engineering applications. It is suggested to further deepen research in the following aspects: quantitative analysis methods and error correction techniques for similar theoretical errors in aero-elastic model tests.
