We obtain from relation (3.1): c = 20 + 10 = 30 mm . nom The concrete cover for the stirrups is “dominant”. In this case, the concrete cover for longitudinal bars is increased to: 25 + 8 = 33 mm .

EC2 – worked examples 4-3 EXAMPLE 4.2 [EC2 clause 4.4] Design the concrete cover for a reinforced concrete beam placed outside a residential building situated close to the coast. The exposure class is XS1. We originally assume concrete with strength class C25/30. The longitudinal reinforcement bars are 5φ 20; the stirrups are φ 8 at 100 mm . The maximal aggregate size is: dg = 20 mm (< 32 mm). The design working life of the structure is 50 years. A normal quality control is put in place. Refer to figure 3.2. From table E.1N - EC2 we find that, in order to obtain an adequate concrete durability, the reference (min.) concrete strength class for exposure class XS1 is C30/37; the concrete strength class must therefore be increased from the originally assumed C25/30 to C30/37, even if the actions on concrete were compatible with strength class C25/30. Table of Content Fig. 4.2 In accordance with what has been stated in example 3.1, we design the minimum concrete cover with reference to both the stirrups and the longitudinal bars. The structural class is S4 We obtain ( c min,dur = 35 mm ; Δc dev = 10 mm): - for the stirrups: c nom = 45 mm ; - for the longitudinal bars: c nom = 45 mm . The concrete cover for the stirrups is “dominant”. In this case, the concrete cover for longitudinal bars is increased to: 45 + 8 = 53 mm .
