Analysis of Reliability Parameters of Structures of Frame-Cantilever Coverings over Stadium Stands
Abstract: The article discusses stationary frame-cantilever over the stadium stands. Namely, the influence of stochastic variables such as deviations in the geometric characteristics of rolled metal, snow load, subsidence of the base and strength properties of steel on the reliability of the structure. The technique of a simplified approach to calculating the reliability characteristics of a system based on an analysis of the reliability characteristics of the group of the most critical structural elements is considered. The most rational method for calculating the probability of structural failure has been determined. The main parameters affecting the reliability of the system, and methods for taking them into account when determining the reliability characteristics, are substantiated. An algorithm for determining the group of the most critical structural elements and analysis of the survivability of the structure is given. An algorithm is proposed for the numerical determination of the system reliability characteristics based on the finite element method. It has been carried out the analysis of reliability of bearing structures covering over the stands, using variable parameters in the form of departure the console, step frames, angle coverage to the horizon. The analysis was carried out taking into account both separately acting factors, and with joint accounting. For a numerical experiment, the above algorithms are implemented in the MATLAB programming language.
Keywords: building construction, frame and cantilever of the roof above the stands of the stadiums, reliability, stochastic value.
