Rational calibration of three IEC extreme load cases

Research output: Chapter in Book/Report/Conference proceeding › Article in proceedings › Research

Abstract

This paper presents a rational and consistent calibration of the IEC 61400-1 extreme load cases EOG, EWS and ECD based on a system of asymptotic statistical models on closed form. The models are based on simple and easily accessible mean wind speed and turbulence characteristics of the atmospheric boundary layer. Using the wind climate characteristics prescribed in the IEC 61400-1 code as input to the statistical model complex ensures consistency between the specified wind climate and the proposed extreme gust amplitudes. Differences and equalities between the present IEC specifications and proposed specifications of the extreme load magnitudes are highlighted and discussed using an illustrative example based on two selected terrain types.
