Extreme　winds,　such　as　typhoons,　can　lead　to　serious　vibration　and　damage　for　flexible　membrane　roofs.　An　understanding　of　the　aeroelastic　behavior　experienced　by　membrane　structures　during　typhoons　is　therefore　significant　to　allow　well　designed　in　practice.　This　paper　investigates　the　aeroelastic　response　of　umbrella　shaped　membrane　structures　under　typhoon　experimentally　and　numerically.　The　flexible　scaled　model　is　tested　in　typhoon　field　simulated　in　wind　tunnel　to　investigate　the　aeroelastic　characteristics　varying　with　wind　velocities　and　wind　directions,　including　displacement　response,　non-Gaussian　characteristics,　frequency,　modal　shape　and　damping　ratios　et　al.　The　full　coupled　fluid-structure　interaction　numerical　model　proposed　is　benchmarked　and　expanded　in　parameter　discussions.　The　results　indicate　that　non-Gaussian　characteristics　appear　significant　with　positive　skewness　in　pressure　region　and　negative　skewness　in　suction　region.　The　probabilistic　distribution　proves　leptokurtic　type　with　kurtosis　beyond　three.　The　displacement　response　in　statistics　increases　almost　linearly　with　wind　velocity　while　the　non-Gaussian　characteristics　remain　robust.　The　high-order　mode　shapes　can　be　excited　in　typhoon,　and　their　frequencies　and　damping　ratios　vary　with　wind　velocities.　The　effects　of　both　wind　velocity　and　membrane　pretension　are　proved　to　be　more　remarkable　than　rise-span　ratio.　This　study　can　address　the　deficiency　of　current　studies　and　provisions　on　the　dynamic　response　of　membrane　structures　in　typhoons.
