This　paper　presents　the　wind　tunnel　test　and　numerical　simulation　on　umbrella-shaped　tensioned　membrane　structures　to　investigate　the　effects　of　both　high　wind　velocity　and　various　wind　direction　of　typhoon　on　their　aerodynamic　behavior.　Finite　element　models　are　also　developed　and　benchmarked　to　further　investigate　the　effects　on　rise-to-span　ratio,　wind　attack　angle,　and　pretension.　Results　from　the　experimental　tests　and　finite　element　analyses　show　that:　(i)　the　turbulence　buffeting　in　the　leeward　surface　is　significant　with　large　displacement　responses,　especially　with　the　0　degrees　wind　direction,　large　wind　attack　angle　and　high　rise-to-span　ratio;　(ii)　Non-Gaussian　characteristics　become　remarkable　with　increasing　skewness　and　kurtosis,　which　may　be　contributed　by　the　high-level　turbulence　intensity　in　typhoons;　and　(iii)　the　effects　of　rise-to-span　ratio,　wind　attack　angle　and　pretension　are　proved　more　significant,　which　should　be　considered　in　the　wind-resistance　design　of　membrane　structures　in　typhoons.
