Effort analysis of reinforced concrete columns using dynamic relaxation method
Journal Title: Bulletin of the Military University of Technology - Year 2014, Vol 63, Issue 2
Abstract
The method of the analysis of static deformation of reinforced concrete columns with regard to geometrical nonlinearity of the columns and physical nonlinearity of structural materials was presented in the paper. For reinforcing steel, the elastic-plastic model of material with material hardening was applied. The elastic-plastic model of material with material softening was used for concrete. The method of effort analysis of the structural system was developed using the finite difference method. The effective dynamic relaxation method for solution of the systems of the equilibrium equations of reinforced concrete columns was developed. It was the basis for preparation of the own numerical procedures and numerical program. The reinforced concrete simple supported columns, under eccentric compression, were numerically analysed. The numerical results were compared with experimental results, taken from literature, and with theoretical solutions.[b]Keywords[/b]: mechanics of structures, reinforced concrete columns, physical nonlinearity, geometrical nonlinearity
