Cable net roofs with hyperbolic-paraboloid shape: structural behaviour, aerodynamics and aeroelasticity

The research examines the structural engineering challenges related to the assessment of the wind-induced action and deformation of lightweight, hyperbolic-paraboloid cable-supported membrane roofs. The study examines several different roof geometries (square, rectangular and circular) and two distinct membrane curvatures for each geometry. Furthermore, wind directionality (three mean-wind incidence angles) and Reynolds number effects (seven mean wind velocities) are studied. The goal is to better describe the complex fluid-structure interaction of the roof membranes, which can only be achieved by both, aerodynamic and direct aeroelastic tests.
