Info

Using the greater value:

s yk bdf

Use T12 @ 250 mm crs. (452 mm2/m) bottom in column strips

Using the middle strip moment for the first interior span b = 4.725 - 2.36 = 2.365 m (average panel width)

MSd,ms = 0.45 x 123 x 106 = 0026 bd2f. ~ 2365 x 1752 x 30

Use T12 @ 300 mm crs. (377 mm2/m) bottom in middle strips

Minimum longitudinal reinforcement, using dmax = 195 mm 0.6 bd
