In　order　to　determine　the　difference　and　similarity　of　along-wind　loads　of　high-rise　buildings　between　Chinese　Taiwan　and　Chinese　mainland　areasbenchmarking　analysis　was　used　to　compare　the　wind　load　code　for　buildings　on　both　sides　of　the　Taiwan　straitand　multi-factor　analysis　of　along-wind　loads　of　high-rise　buildings　was　conducted　using　the　uniform　design　method.　The　results　show　that　there　are　significant　differences　in　the　basic　wind　speed　sample　method　and　extreme　distribution　parameter　estimation　methods.　The　wind　pressure　height　coefficient　distribution　and　conversion　coefficient　of　design　wind　speed　in　different　return　periods　for　the　two　standards　are　roughly　the　sameThe　turbulence　intensity　values　of　the　Taiwan　code　is　significantly　larger　than　that　of　the　mainland　codeFor　the　wind　pressure　calculation　of　main　wind-force　resisting　system　and　cladding　Taiwan　wind　load　code　adopts　classification　methodwhile　the　Mainland　wind　load　code　adopts　a　unified　expression.　There　are　significant　differences　between　the　two　standards　in　the　combination　of　design　wind　loads　of　along-windcross-windand　torsional　directions.　Taking　the　base　shear　and　base　bending　moment　as　evaluation　indexesthe　influence　of　aspect　ratio　H　BLexposure　factor　αgust　effect　factor　Cgwind　load　shape　coefficient　Cp　and　turbulence　intensity　Iz　on　the　along-wind　loads　of　high-rise　buildings　gradually　decreasesand　the　aspect　ratio　and　exposure　factor　are　the　main　influencing　factors.　The　influence　of　gust　effect　factor　on　along-wind　load　increases　with　the　increase　of　the　aspect　ratio　of　the　structureand　when　the　aspect　ratio　increases　to　a　certain　valueit　becomes　the　main　factor　that　dominates　the　along-wind　loads　of　the　both　sides.　©　2023　Science　Press.　All　rights　reserved.
