Info

Either limit bar size to EC2 Table 4.11 value or bar spacing to EC2 Table 4.12 value.

From Table 4.12 bar spacing < 270 mm < 275 mm used Check minimum reinforcement requirement

For y4ct it is considered conservative to use (h/2)b. a = 100% x r = 460 N/mm2

s yk

For faeff use minimum tensile strength suggested by EC2, 3 N/mm2 kc = 0.4 for bending k = 0.5 for h > 80 cm Therefore
