Energy portrait of the structural system as a criteria for option design

Problem. The article proposes the use of energy analysis to describe deformation characteristics structural system, and specifies criteria that form basis BEO method, which allows for an engineering assessment quality designed load-bearing structures. Goal. goal is implement spread adaptation variant design problem. theoretical approach construction portrait structure. Methodology. To this approach, calculations were made three variants superstructure existing five-story building, a prefabricated reinforced concrete frame II-22...II-24 series. A monolithic frame, metal as well with overlap covered steel-reinforced structure new type are adopted options. In order comprehensively consider described in give proposed positive qualities, auxiliary task was additionally considered, namely, inclusion shear ties connecting upper belt slab.. Results. comparison solutions carried out by comparing consumption materials required superstructure, components stress-strain state, values ​​of introduced criteria. Originality. On calculations, results frames different options presented. potential density fields slabs under action uniformly distributed load received technical economic indicators accepted determined formulated conclusions. Practical value. Energy behavior set loads nature, effective procedure evaluating examining project (variant design), their rationality, building durability forecast.
