Original Abstract

The problem of current complex nonlinear material models of concrete is that they very often contain a large number of material parameters which is difficult to define without the specialized tests of concrete or without the perfect knowledge of the material models theory. These parametrs are, however, often very important for the correct function of the material models. The mentioned problem can be currently solved by performing the inverse analysis. The inverse analysis allows to find such values of the identified material model's parameters at which the data obtained from the numerical simulation provide very good approximation of the experimental data. The aim of this paper is to perform the inverse identification of the parameters of nonlinear concrete material model with and without the reduction of the initial design vector which contains the identified material parameters and subsequent comparison of the results.
