Windstorm: Gusts at return period 50 years
This dataset provides Swiss windstorm risk maps showing peak wind gusts and their associated dynamic pressure for a 50-year return period, together with corresponding uncertainty estimates. Published by the Swiss Confederation, likely through the Federal Office for the Environment (BAFU), it offers a nationwide basis for assessing regional windstorm risk across Switzerland. The maps are intended to support risk estimation but do not replace the Dynamic Pressure Reference defined in Standard SIA 261 Annex E, which remains the authoritative technical reference for structural design purposes.The Windstorm Risk Maps show peak wind gusts and their dynamic pressure and the corresponding uncertainties. The maps provide a country-wide basis for the estimation of the regional windstorm risk, however they do not replace the Dynamic Pressure Reference (Standard SIA 261 Annex E). The windstorm…
