« c ct.eff s ct where k = 0.4 assuming value for bending is to be used k = 0.5

'cteff = 3 N/mm2 using suggested value a = f = 460 N/mm2

Hence

The requirements of either Table 4.11 or Table 4.12 of EC2 should be met.

Assume steel stress = x value for main bars = 94 N/mm2 4.4.2.3(4)

Table 4.11

Maximum bar size

Maximum bar spacing in 'pure tension' condition Table 4.12

s max

Use T10 @ 150 mm crs (EF) above level of main reinforcement
