EC2 – worked examples 6-37 The compressive range for each strut (only exception, the strut C1, which stress has been verified before in the forces evaluation for the region B) can spread between the two ends, in this way the maximal stresses are in the nodes. The transversal stress for the split of the most stressed strut (C2) is: Ts ≤ 0.25·C2 = 0.25 1647 = 412 kN; and then, for the reinforcement required to carry this stress: 412000 A 1053 mm 391.3 2 s = = , then the minimum reinforcement (1 φ 12 / 20” on both sides and in both directions, that is a s = 1130 mm 2 /m) is enough to carry the transversal stresses.
