| Title of the article | Investigation of the convergence of determining the resource elements of the structure in terms of modeling the values of random parameters of the reserve strength |
| Abstract. | Problem statement. The purpose of the study is to determine the impact of environment simulation values of random parameters calculation results strength reserve resource as individual elements of core facilities and the whole structure repeated lowcycle static loadings. You intend to define the resource at the design stage of a construction as the number of repetitive cases before exhausting the reserve strength in two-way tolerant assessment of its value. Given the random characteristics of the influences on the one hand and the bearing capacity of the elements on the other hand, as well as the availability of interval only the values of the parameters characterizing ultimately define the random variable reserve strength, reliability of the results can depend largely on modeling not only distribution of efforts in the elements. Results. The main results are that the study reserve strength as a random value by building his nomogramm with different input data for modeling of stationary stochastic process allows you to analyze and make reliable conclusions on the convergence results in resource definition depending on the properties of both the model and its simulation. As to the preliminary calculation of the minimum element and resource structures as a whole was adopted by the condition zero exhaust the reserve strength of at least one element of the structure. Conclusions. The significance of the results obtained for the construction industry is that at the initial stage of design study changes reserve strength elements allows you to define and regulate the minimum design resource with a specified reliability not appearing in at least one failure element designs with repeated static loads. |
