Wind-Induced Response in Membrane Structures

Membrane structures—lightweight surfaces that rely on in-plane tension for load resistance—are increasingly employed in applications such as stadium canopies, airport terminals and temporary shelters. Their minimal bending stiffness and high flexibility render them particularly sensitive to wind loads, which manifest as steady pressures, turbulent fluctuations and discrete gusts. The interaction between aerodynamic forces and membrane deformation gives rise to fluid–structure interaction phenomena, including vortex shedding, limit-cycle oscillations and aeroelastic instabilities. Understanding these effects is essential for safe and economical design, especially in regions prone to extreme weather events. Recent work combines wind-tunnel experiments, digital image correlation and advanced computational methods—such as large-eddy simulation and partitioned coupling algorithms—to characterise pressure distributions, modal properties and damping behaviour. These insights support the formulation of equivalent static design methods, optimisation frameworks and material selection strategies, ensuring that membrane structures remain both resilient and resource-efficient under diverse wind conditions.

Experimental studies on hyperbolic paraboloid tensile roofs in simulated typhoon conditions have shown that elevated turbulence intensities significantly increase maximum deflections and alter probability distributions of displacement, leading to reduced damping and heightened risk of aeroelastic instability. Modal analysis reveals shifts in natural frequencies and mode shapes as wind intensity increases, informing reliability assessments in hurricane-prone regions. Investigations into spherical inflatable membrane structures have employed nonlinear dynamic time-history analyses based on wind-tunnel pressure measurements to demonstrate how geometric parameters, internal pressure and cable configurations influence displacement patterns. Key findings include a windward shift of peak deflections under high speeds and a trade-off between reduced deflection through higher inflation pressure and increased membrane stress. Complementary research on air-supported cable-membrane systems highlights the role of frictional contact: varying cable-to-membrane friction coefficients alters the form-finding process, load transmission and deformation under gusty winds. Comparative simulations show that higher friction intensifies local stress concentrations, guiding choices of membrane materials and detailing for large-span roofs.
