Response of a Double Hypar Fabric Structure Under Varying Wind Speed Using Fluid-Structure Interaction

Wind effects on tensile fabric structures (TFS) are not extensively investigated. Available studies consider simplified TFS support conditions and comparisons between static dynamic analyses lacking. The response of a double hypar under varying wind speed is carried out by using fluid-structure interaction (FSI). Realistic considered. geometry determined through form-finding. Computational fluid dynamics (CFD) the basis to perform analysis propose pressure coefficients useful for design. Differences assessed. It found that stresses in axial forces supports significantly different each type analysis, which cannot be captured uniform uplift snow loadings. Static leads differences up 17.3% fabric, 10.5% compressive force masts 33.5% cables, compared FSI analysis. Results give further insight into realistic TFSs.
