Original Abstract

The paper is focused on statistical inverse analysis of material model parameters, where statistical parameters of input parameters of input parameters have to be identified based on experimental data (histograms of response). Stratified simulation technique of Monte Carlo combined with artificial neural network is efficiently used. The methodology is shown using example of reinforced concrete frame. means and standard deviations of fracture-mechanical parameters (like modulus of elasticity, fracture, energy, etc.) are subject of identification. The paper shows differences in results when using different load levels for identification.
