Essay

A mathematical models were created for calculating of the stability of high-rise constructions in the form of multisectional bars of constant and variable cross-section and high-rise construction of drilling tower. Mathematical models were extended to the cases of modal analysis of high-rise constructions due to the common problems of stability and free vibrations. Considered the stress-strain state and loss of stability of triplesectioned construction of the pipeline, which includes aboveground and the related underground sections and is under temperature stress. The mathematical model multisectional high-rise construction was created for calculation of dynamic stability by reducing the equations of motion to a system of differential Mathieu equations.
