Sirobaba V. Bearing capacity and deformability of steel reinforced concrete structures made of lightweight concrete

The object is the compression of steel reinforced concrete constructions made of lightweight concrete; the purpose is to determine the bearing capacity and deformability of steel reinforced concrete structures made of light concrete; The novelty is the further development of structural solutions of steel reinforced concrete racks with the help of lightweight steel thin-walled elements filled up with lightweight concrete; new data of experimental research of load carrying capacity and deformability of steel reinforced concrete stressed elements have been received; the method of numerical modeling of work on compression of steel reinforced concrete constructions made of lightweight concrete has been developed; it gave the opportunity to determine their bearing capacity and deformability; the engineering methodology for evaluating of bearing capacity at the compression of steel reinforced concrete constructions has been developed by applying of proposed coefficients which take into account the work of lightweight concrete in a steel shell clip; The results a proposed coefficient of work conditions for taking into consideration the heterogeneity of the physical and mechanical properties of concrete of pipe concrete elements, as well as recommendations as for the technology of filling up the pipe - shell with concrete have been studied at the construction site; The branch is - construction
