Without concrete stress-strain curves based on the results of experiments obtained using test prisms and test cylinders it is difficult to evaluate the compliance of the ultimate strain of concrete with the peak load and the descending arm load at the level of 0.85Rb. In this paper, an attempt was made to experimentally verify curves σ-ε. Specimens made as one batch of the same concrete mix were tested using same methods. The test results showed that the difference in ultimate rates of strain is minor, and the analytical description of the curves obtained on prisms and cylinders corresponds to the results of testing not only at the peak load points and descending arm at the level of 0.85Rb, but also at intermediate values.
