摘要：When stresses in concrete in reinforced concrete beams with the reinforcement ratio being high due to the ultimate limit state are calculated – according to the linear elasticity theory – from strains of a characteristic combination or even a quasi-permanent one, in some cases compressive stresses in extreme concrete fibres can be even higher than the characteristic compressive strength of concrete. In the following report, it is postulated to calculate these stresses with the help of the non-linear stress-strain relationship for concrete. It has also been demonstrated that the requirements specified in points 7.2(1)P and 7.2(2) of the standard PN-EN 1992-1-1:2008/NA:2010 Eurocode 2:Design of concrete structures. Part 1-1: General rules and rules for buildings, are useless and do not suit the limit state analysis, on which Eurocodes are based.
