A Study on Actual Wind Load Distributions Derived by Advanced Conditional Sampling Method

Recently, LC (load combination) method was developed by Holmes as a general method to derive effective wind load distributions (EWLD) for all types of structures. The LRC method used in the LC method, however, neglects resonant effect in developing background component of the EWLD. Also, it couldn't consider properly non-Gaussian pressures. The results of the LC method could be therefore quite different with actual wind load distributions (AWLD). In this study, advanced conditional sampling (ACS) method was developed to derive the AWLD and the EWLD was compared with it for a slender structure and a large span roof. Furthermore, a modifed method is suggested to compensate shortcomins of the LC method for convinient and practical use.
