Abstract

The main subject of the paper is the application of the homogenisation method to the analysis of the elastostatic problem for the steel reinforced concrete plate. The upper and lower bounds on the effective elasticity tensor components as well as direct approximation of the tensor are used to build up the computational model of the structure. The results of numerical analysis are compared against the experimental data. The convergence of experimental and computational data for the real and homogenised composite plate confirms the effectiveness of the homogenisation method applied in the analysis of steel-reinforced uncracked concrete structures. To verify the generality of this approach, analogous tests should be carried out for other types of engineering composite structures, especially in continuous non-linear range.
