In　order　to　observe　the　influence　of　the　random　noise　of　wind　velocity,　by　using　a　real　high-rise　building　example　of　wind-structure　interaction　analysis　based　on　ANSYS,　the　dynamic　response　of　the　high-rise　building　under　the　artificial　time　history　of　wind　velocity　is　simulated　according　to　power　spectra　with　and　without　random　components　and.　The　comparison　of　the　analytical　results　shows　that　the　dynamic　response　of　the　high-rise　building　has　been　enlarged　to　certain　degree　if　the　random　components　of　the　input　power　spectra　of　wind　are　considered.
