NUMERICAL ANALYSIS OF BEHAVIOUR OF REINFORCED CONCRETE ELEMENTS UNDER ECCENTRIC COMPRESSION

Abstract

Paper presents results of numerical modelling of behaviour of plane strain reinforced concrete elements under eccentric compression. In the analysis, a finite element method was used based on an elasto-plastic constitutive law by Drucker-Prager with hardening and softening for concrete and an elasto-plastic constitutive law by von Mises for reinforcement. The effects of boundary conditions at the element ends, eccentricity of the compressive load, element slenderness, area of the longitudinal and horizontal reinforcement on the load bearing capacity of elements were studied. The effect of the mesh refinement on the bearing capacity of elements was also analysed. A satisfactory agreement with model tests was achieved.
