Sažetak

On the basis of experimental testing of behaviour of concrete, reinforced concrete and prestressed concrete structures, various phenomena were observed; in the first place, highly non-linear and inelastic behaviour of
concrete. Since it is hard to include all the phenomena and changes that occur in concrete, a large number of numerical models for concrete were developed to describe different states of the problem under consideration, with the tendency to include in these analyses the changes that are dominant in the observed problem. This paper will give a brief overview of some characteristic numerical models for concrete, developed so far, with a short overview of their advantages and disadvantages, i.e. possibilities and limitations. The models were classified depending on the formulation of the constitutive laws. Models were chosen to demonstrate the diversity of modelling and specifics of their application.
