STABILITY PROBLEMS OF LARGE SIZED MULTI ELEMENTS ROD STRUCTURES

English abstract

Recently, process of complicating buildings and structures, which is so-called "architectural trend", as well as market competition leads to the construction of insufficiently approved structure forms. The situation is aggravated by the "lagging behind" regulatory framework, unsatisfactory skills of the construction process participants, contravention of the constructed objects operation rules and other negative factors, on the one hand. On the other hand, a number of documents are of a recommendatory nature. Thus, current above-described situation determined the relevance of this publication. There were made the following in order to correctly predict the trouble-free operation of multi-element metal structures: - concepts, principles, qualitative and quantitative indicators of operational efficiency (survivability) and its categories related to nodes, structural elements and technical systems in general were formulated; - a large-scale effect both in the designing and in the operation of large-sized and multi-element metal structures was considered; - emergency metal structures destruction data were nalyzed; - reasons for characteristic defects and rod metal structures damage are considered, including the modeling of damage formation processes, the identification of random physical regularities of the sizes scattering and defects location.
