0.033, x/d = 0.063 (Section 13, Table 13.1) 342 mm2/m

Note:

Reinforcement areas differ somewhat from those given by BS 8110 which permits design for the single load case of maximum load on all spans combined with 20% redistribution. EC2 requires alternate and adjacent spans to be considered. In this instance, no redistribution has been carried out but it would have been permissible to carry out 30% redistribution in the EC2 design. This would have resulted in an identical answer to that given by BS 8110 but ductility class H NAD (as defined in prEN 10080(8)) reinforcement would need to be specified. Table 5
