Wind　tunnel　tests　and　numerical　simulations　are　the　mainstream　methods　to　study　the　wind-induced　vibration　of　structures.　However,　few　articles　use　statistical　parameters　to　point　out　the　differences　and　errors　of　these　two　research　methods　in　exploring　the　wind-induced　response　of　membrane　structures.　The　displacement　vibration　of　a　saddle　membrane　structure　under　the　action　of　wind　load　is　studied　by　wind　tunnel　tests　and　numerical　simulation,　and　statistical　parameters　(mean,　range,　skewness,　and　kurtosis)　are　introduced　to　analyze　and　compare　the　displacement　data.　The　most　unfavorable　wind　direction　angle　is　0　degrees　(arching　direction).　The　error　between　experiment　and　simulation　is　less　than　10%.　The　probability　density　curve　has　a　good　coincidence　degree.　Both　the　test　and　simulation　show　a　certain　skewed　distribution,　indicating　that　the　wind-induced　vibration　of　the　membrane　does　not　obey　the　Gaussian　distribution.　The　displacement　response　obtained　by　the　test　has　good　stability,　while　the　simulated　displacement　response　has　strong　discreteness.　The　difference　between　the　two　research　methods　is　quantitatively　given　by　introducing　statistical　parameters,　which　is　helpful　to　improve　the　shortcomings　of　wind　tunnel　tests　and　numerical　simulations.
