With　the　help　of　Monte　Carlo　stochastic　simulation　algorithm　for　strong　typhoon　and　wind　environment　parameters　suggested　by　Chinese　wind　loading　codes　for　normal　climate　mode,　two　types　of　wind　environment　characteristics　about　typhoon　climate　and　normal　climate　were　calculated.　Then　it　was　demonstrated　with　passive　turbulence　generator　in　atmospheric　boundary　layer　wind　tunnel　TJ-3　at　Tongji　University.　For　Guangzhou　Xinguang　arch　bridge　located　in　the　Southeast　coastlines　prone　to　strong　typhoons　at　constructing　and　working　stages,　wind-induced　vibration　responses　under　various　wind　parameters,　such　as　basic　design　wind　velocity,　wind　profile　and　various　turbulent　degree,　etc.　,　were　compared　in　detail　for　bridge　girder　and　arch　in　mid-span　and　high　rise　steel　tower　used　for　building.　Some　phenomena　about　buffeting　response　difference　mechanism　were　finally　explained.
