The purpose of the work is to develop a new method for detecting the stress-strain state of steel reinforced concrete structures of bridges and their experimental variation. Research methods - modeling of temperature fields in steel-reinforced concrete constructions at standard temperature mode and temperature analysis of run-off structures of bridges under hydrocarbon temperature conditions. The methods of creating a mathematical model of deformation diagram of compressed concrete at elevated and high temperatures have been developed; A new method for determining the stress-strain state in steel reinforced concrete structures for a wide range of buildings and structures, as well as in steel reinforced concrete structures of bridges under the combined influence of loading and elevated temperature with the use of computer technologies in linear and nonlinear formations has been developed; Numerical simulation of the stress-strain state in steel-reinforced concrete structures was conducted; new methods of experimental research, installation and samples of steel-concrete constructions have been developed; Experimental researches of fragment model of steel reinforced concrete bridge construction were conducted.
