METHODOLOGICAL ASPECTS OF ASSESSING THE STEEL FRAMES RELIABILITY

Abstract

The article highlights the proposed algorithm for evaluating the reliability of steel frames. In particular, it is possible to analyze the reliability of the most likely failure mechanism. Separate assumptions that determine the sequence of application of the limit equilibrium method are presented. A method for determining the reliability of statically indeterminate steel frames in the plastic stage is presented. This method provides an opportunity to determine the probable mechanism of destruction. The ultimate equilibrium method is used to calculate the forces at the final stage of destruction. In the work, the real mechanism of destruction is understood as a mechanism for which the work of external forces to create it is the least. It is revealed that the real mechanism of destruction is approaching the beam or floor elementary mechanism.
