Maksymova T. Work of concrete beam structures on deformable foundation

The object of study - a system of continuous reinforced concrete beams on deformable foundation, widely used in the construction of buildings for various purposes; Goal - the creation and implementation numeral-analytical computational model of tensely-deformed state of systems of reinforced concrete beams on deformable foundation; Methods - theoretical and numerical studies of beam systems using numerical-analytical method of boundary elements, analysis of the convergence of results obtained with the experimental results and other authors; Results - first proposed by numerical-analytical computational model deformation system of reinforced concrete beams on the deformed foundation, developed a practical method for determining the stiffness of reinforced concrete elements for short periods of stress, based on proposals by I. Prokopovich, first developed algorithms for automated formation of the matrix and the program of determining the tensely-deformed state of continuous reinforced concrete beams and cross-beam construction on deformable foundation with the use of numerical-analytical computational model of a deformable foundation; novelty - first proposed computational model of continuous deformation of reinforced concrete beams and beam systems deformable foundation, developed and investigated algorithms for solving the equations that describe the computational model, developed programs that allow numerically determine the tensely-deformed state of continuous reinforced concrete beams and beam systems in the deformed foundation taking into account the processes of formation of cracks and the actual properties of soils. introduced - in the design of reinforced concrete beam design multi-storey residential complex with retail and office space and underground parking in the carpool "Tourist" at Odessa, Gagarin plateau, 5-A, in the learning process.
