Question
The cross-section at mid-span of a beam at the edge of a slab is shown in the sketch. A portion of
the slab is considered as the effective flange width for the beam. The grades of concrete and
reinforcing steel are M25 and Fe415, respectively. The total area of reinforcing bar (As) is 4000 mm².
At the ultimate limit state, xu denotes the depth of the neutral axis from the top fibre. Treat the
section as under-reinforced and flanged (xu > 100 mm).
