In the paper the influence of applied concrete class for selected parameters of prestressed main beam was analyzed. The impact assessment was made according to specified criteria. Exacerbation or changing one of the criteria may cause the deterioration or improvement of other conditions. The most important criterion in the assessment is to provide an appropriate loading capacity by fulfilling the necessary conditions of safety, in accordance with the relevant standards and regulations. In this paper limit state on crack width, safety condition of cracking limit state at a given level of losses and allowable compression stress limit for prestressed concrete were evaluated. In this article the concrete which satisfy given assumptions was specified.
Keywords: concrete class, limit states, prestressed beam, optimalization.
