Figure 7.23. Slenderness ratio as a function of the concrete grade Influence of the tensile strength of concrete (fctm vs. fctm,fl)

The final version of prENV, allows the use of the flexural tensile strength of concrete instead of the mean tensile strength for the calculation of deflections. This topic was subject of much controversy and it is therefore interesting to test the differences to which this may lead. For this purpose, the slenderness limits were redetermined with the assumption that the flexural tensile stress of concrete could be used. The results are shown in Fig. 7.24.
