This paper presents a proposal for determining Strut-and-Tie models of reinforced concrete plane elements. For the purposes of analysis, a computer program was developed and a discrete topological optimization was applied, using a truss member for the design of the stress-strain state of the real member. The method can be used for the analysis of a part or a whole member and it is particularly suitable for the usage in the places of sudden changes of static and/or geometric characteristics of members. The general principle of the method is that compressed members replace concrete parts of the element (surface or volume) and tension members replace the reinforcement.
