Simulation of straining plate members of reinforced concrete structures for heat-power engineering constructions using finite-element method
Journal Title: Технічна механіка, Техническая механика, Technical Mechanics - Year 2015, Vol 2, Issue 2
Abstract
The work objective is to study of a stressed-strained state of plate members of reinforced concrete construc-tions for heat power engineering with arbitrarily oriented extended inclusions depending on a combination of the stiffness parameters of inclusions, their sizes and orientation, relations of stiffness of inclusions and the plate. Projection-iteration modifications of the finite-element method are employed. Parametric characteristics of stressed-strained states of a concrete matrix and reinforcement bars of plate constructions with a rectangular cut are obtained for different compressible loads and reinforcement coefficients. Problems of the determination of the limiting load values resulting in plastic strains and cracks are discussed. Programs for calculating the above parameters are developed.
