STUDY OF RELIABILITY AND DURABILITY OF FRAME ELEMENTS OF BUILDINGS

The article deals with the study of issues of probability regarding frame elements of buildings. Durability of these frame elements are investigated taking into account the accidental character of loadings and features of used materials. The question of durability with considering the increase of damages is investigated. The expression of module of rigid and plastic component is given. The numerous experiments implemented by the author over concrete samples enabled him to analyze the process of tempering of concrete and compile a schedule of corresponding distribution of probability. The corresponding schedules and histograms are compiled by various concrete samples.
