The determination of characteristic values for design can also be achieved by developing characteristic substitute loads, as described in the WTG Wind Tunnel Guideline. The challenge here is to identify the most unfavorable load combination and to assess the simultaneous occurrence of extreme values.
For reliable calculation of local suction peaks and fluctuating loads, which are particularly relevant for the local stress on wall and roof claddings, solar installations, and small-format components, it is essential to analyze time series in relation to the load collection area. These detailed loads cannot be adequately extrapolated from average values.
