The generalized load statistical parameters’ assessment on the building structures

Abstract

The distribution laws’ composition of the permanent, long-term temporary, snow and wind loads acting on the structure of buildings and structures is estimated. The following load distribution laws are respectively adopted: normal, logarithmically normal, Gumbel and Weibull. The calculation of the four main central statistical moments was carried out, the approximate distribution law for the generalized load was established by the expansion method in a Gram-Charlier series, as well as the magnitude of its statistical variability. The characteristics of the load variability are compared with the approximate solution of A.N. Dobromyslov. The results obtained are intended for the practical solution of the problems of assessing the safety and residual life of buildings and structures using the reliability theory methods.
