Анализ вероятности отказа конструкции на основе приближения хвостовых частей распределений случайных величин нагрузки и сопротивления

Abstract

The article discusses the analysis of the reliability of the structure, which is performed on the example of the calculation of a compressed reinforced concrete column, in which the state of the column X is determined as the difference between itscompression resistance R and the external compressive load E. Three calculation methods are considered: the semi-probabilistic method, probabilistic-statistical modeling, and solving the problem of analyzing the state function not in the entire domain of its definition, but only for the condition X=R-E<0 that corresponds to the overlap interval of the functions g(E) and g(R).
