Modelling of inelastic behaviour of reinforced concrete deep beam
Journal Title: Journal of Achievements in Materials and Manufacturing Engineering - Year 2016, Vol 74, Issue 1
Abstract
Purpose: An analysis of the static load - carrying capacity of rectangular reinforcedconcrete deep beam taking into account the physical nonlinearities of structural materials:concrete and reinforcing steel, was the aim of the paper.Design/methodology/approach: The model of the elastic-perfectly plastic material wasapplied for the reinforcing steel. The reduced, static form of non-standard model of dynamicdeformation, with regard to the material softening was applied for the concrete. The methodof structure effort analysis was developed using the finite element method.Findings: The results of numerical solutions were presented with comparison to theexperimental results and other numerical results taken from the literature. Very goodagreement of the numerical results was obtained in comparison with the experimentalresults in the range of the load - carrying capacity and the displacement state analysis.Research limitations/implications: The effectiveness of the method analysis andcomputational algorithms for the problems of numerical simulation of reinforced concretedeep beam behaviour was indicated in the paper.Practical implications: The developed method can be applied to the effort analysis ofthe different reinforced concrete structural elements behaving in the complex stress states.Originality/value: The stress state in the deep beam was illustrated in the form of thestress distribution over the characteristic cross-sections as well as in the form of the schemeof the material effort on the surface of the structure.
