Developing estimation algorithm of reliability indicators of industrial buildings

In terms of developing automated system of calculating and forecasting the residual life of industrial buildings the article compares the advantages and disadvantages of reliability models of industrial buildings. The scheme of examining mode of deformation of an industrial building has been created. Realization of successive actions helps to determine the terms of achievement of the limiting conditions of an industrial building, to estimate the reserve strength of its carcass, and to search for changes in the amplitude values of the displacements in the calculated points, according to the results of comparative analysis of corresponding values in different periods of industrial building operation at a constant value of the generalized load. There has been carried out comparative analysis of computer-aided design systems that revealed the need to develop the proper software product specialized in calculating the work of industrial structures equipped with electric bridge cranes, with a whole complex of disturbing effects. According to the results of calculation scheme there was developed a summary algorithm which implemented the possibility of solving direct, inverse and predictive problems, as well as realizing probabilistic approach as most appropriate for random nature of man-made and natural impact, and for the conditions of their perception. Summary algorithm generates the values of crane loads in the form of continuous random values in accordance with the distribution law for the given parameters of expectation and mean-square deviation. It enables to carry out comparative analysis of the obtained probabilistic values and results of the calculation of the normative values of loads under constant conditions of the system operation. This algorithm is the basis of the development of the settlement and software complex "ASR-2018".
