Abstract

An approach to estimate the wind load spectra for heliostats is proposed. It is based on the wind-induced fatigue cycle counts for buildings given by the Eurocode EN 1991 and considers heliostat specific impact factors. The approach can be further refined if data on specific wind and heliostat field properties are available.
