Alexeyenko B. Structural analysis and optimal design of framed structures, which are operating in aggressive environments

The mathematical models of stress-strain state analysis and durability of framed structures, which operate in aggressive environments, with discretization by method of finite elements, have been developed – by its linear statement and by deformed scheme. The model of seasonal variance of temperature has been developed. This allows to refine the analysis for cases of corrosive wear. The discrete method of optimal design of truss and framed systems, which are subject of corrosion wear, has been developed. It considers all the distinctions of the problem and allows to apply the existing standards during all the stages of design. The numerical experiment has been performed and the influence of properties of aggressive environment as well as stress level on the durability and optimal properties of framed structures has been researched.
