FEATURES OF MODELING THE OPERATION OF REINFORCED CONCRETE STRUCTURES USING INCONSISTENT FINITE ELEMENT MODELS
Main Article Content
Abstract
his article is devoted to the development of inconsistent finite element models of reinforcing rods for strength analysis of reinforced concrete structures. Currently, reinforcement in the calculations of reinforced concrete structures is taken into account using various methods. The authors pay special attention to the embedded finite element model. The article discusses mathematical models and technology for the output of stiffness matrices of reinforcing rods embedded in finite elements of various configurations. Using the derived finite elements, a number of comparative test calculations of reinforced concrete beams were carried out. Numerical solutions on inconsistent FE grids were compared with the results obtained on a consistent finite element grid.
