For a T-beam, the effective flange width (bf) as per IS 456 for an intermediate beam is:
RCCRCCMEDIUM
Choose the correct answer
A
Equal to the full slab width
B
Minimum of L0/6 + bw + 6Df; c/c distance; and actual flange width
C
Only bw (web width)
D
2 × bw
Correct Answer
B. Minimum of L0/6 + bw + 6Df; c/c distance; and actual flange width
Why is this the answer?
IS 456 Cl. 23.1.2: For T-beam, bf = minimum of: (i) L0/6 + bw + 6Df; (ii) centre-to-centre distance between beams; (iii) actual flange width. Where L0 = effective span, bw = web width, Df = flange (slab) thickness. The T-beam action relies on the slab acting as compression flange.
