Note: The value of k 1 for use in a Country may be found in its National Annex. In the absence of other measures, such as an increase in the cover to reinforcement in the compressive zone or confinement by transverse reinforcement, it may be appropriate to limit the compressive stress to a value k 1
Such cracking may lead to a reduction of durability. (2) Longitudinal cracks may occur if the stress level under the characteristic combination of loads exceeds a critical value. (1)P The compressive stress in the concrete shall be limited in order to avoid longitudinal cracks, micro-cracks or high levels of creep, where they could result in unacceptable effects on the function of the structure.
