Моделювання напружено-деформованого стану балкової клітини, що зазнала ушкоджень внаслідок нерівномірних просідань фундаметів, для розроблення раціональних заходів із підсилення

Abstract

In this article had been developed effective methods of modeling the tensely-strained condition of steel frame of structural stand uploaded static and dynamic (seismic) forces subject to geometrical nonlinearity and non-flatness levels of columns bases, which were simulated as possible irregular subsidence of foundation; had been done adequate super-elements models by Lira 9.4; had been discovered the most loaded parted of structural stand, had been offered recommendations to improve the construction of strengthening.
