To　clarify　the　reasonable　values　of　along-wind;　loads　on　high-rise　buildings　between　Chinese　Taiwan　and　Chinese　mainland,a　comparative　analysis　was　conducted　based　on　wind　load　distribution　and　base　response　calculated　according　to　the　standards　of　both　sides.　Additionally,a　rigid　model　pressure　measurement　wind　tunnel　test　was　performed　to　evaluate　the　safety　of　the　along-wind　load　values.　The　results　show　that　as　the　height-to-width　ratio　of　the　structure　and　ground　roughness　decreases,the　calculated　along-wind　loads　in　both　standards　gradually　increase.　However,the　increase　in　the　standard　of　Chinese　Taiwan　is　pronounced　than　that　in　the　standard　of　Chinese　mainland.　Specifically,as　the　height-to-width　ratio　increases　and　ground　roughness　decreases,the　calculated　wind　loads　in　the　standard　of　Chinese　Taiwan　are　relatively　high.　Furthermore,as　the　height-to-width　ratio　increases,the　gust　response　factor　in　the　standard　of　Chinese　Taiwan　gradually　increases,　while　the　equivalent　wind　vibration　coefficient　in　the　standard　of　Chinese　mainland　remains　essentially　unchanged.　The　primary　source　of　the　in　along-wind　loads　between　the　two　standards　is　the　variation　in　methods　for　determining　the　structural　dynamic　amplification　factor.　For　wind　fields　under　the　terrain　category　A,B　and　C,of　the　standard　of　Chinese　Taiwan,wind　tunnel　test　reveals　that　the　shape　of　the　along-wind　load　distribution　aligns　closely　with　the　standard　of　Chinese　Taiwan　but　differs　significantly　from　the　standard　of　Chinese　mainland.When　the　extreme　along-wind　base　response　derived　from　the　wind　tunnel　test　is　used　as　a　benchmark,the　relative　error　dispersion　of　values　in　the　standard　of　Chinese　Taiwan　is　noticeably　larger　than　that　in　the　standard　of　Chinese　Taiwan.　The　results　suggest　that　when　the　height-to-width　ratio　is　smaller,the　standard　of　Chinese　mainland　yields　relatively　safer　results,while　the　standard　of　Chinese　Taiwan　provides　safer　results　when　the　ratio　is　larger.　©　2025　Science　Press.　All　rights　reserved.
