Determining　the　extreme　values　of　wind　loads　is　crucial　for　wind-resistant　design　of　structures.　The　Hermite　polynomial　model　(HPM)-　based　translation　method,　which　uses　the　first　four　moments　of　wind　load,　is　the　most　recognized　and　widely　used　method　for　extreme　wind　load　estimations.　In　this　study,　a　quartic　HPM-based　translation　method　for　estimating　extreme　wind　loads　is　proposed.　A　strategy　for　solving　the　shape　coefficients　is　suggested　for　better　practical　use.　The　monotonic　increasing　condition　required　for　the　translation　between　non-Gaussian　wind　load　and　standard　Gaussian　process　is　discussed,　based　on　which　the　constraint　of　shape　coefficients　governing　the　applicability　of　the　quartic　HPM　is　derived.　From　the　validation　study,　it　is　found　that　the　applicability　of　the　quartic　HPM　is　satisfactory.　Compared　with　the　cubic　and　improved　HPMs,　the　quartic　HPM　stands　out　for　yielding　more　accurate　estimates　of　extreme　wind　loads.　Comparative　analysis　with　the　XIMIS,　an　observed-maxima　method,　reveals　the　quartic　HPM＇s　consistency　in　estimating　extreme　wind　loads　from　data　with　shorter　periods,　while　the　performance　of　XIMIS　deteriorates　with　decreasing　periods.　Furthermore,　the　quartic　HPM　exhibits　robustness　in　addressing　strong　non-Gaussian　wind　loads,　outperforming　the　other　methods　under　such　conditions.　©　2024　Elsevier　Ltd
