Popis: The paper gives the results of the analysis in the probabilistic statement for the remaining life of the roof trusses in the main building of R-1 OAO «Vulture» as of a multi-element redundant system on the basis of empirical function of the reliability index reduction. The time of operation before reaching the set reliability level is considered as the service life parameter. The risk function of the “eaves girder - roof truss” system with regard to the reduction of strength reserve and probability of exceedance of snow load design value was obtained. The suggested method does not require carrying out a direct probabilistic analysis of the building structures and can be realized in the engineering practice in the process of standard instrumental examination of structures.
