Choose the correct answer
A
120 cm
B
150 cm
C
180 cm
D
300 cm
Correct Answer
B. 150 cm
Why is this the answer?
According to IS 456:2000, effective flange width bf = (lo/6) + bw + 6Df. Here, lo = 0.7 * span = 350 cm. bf = (350/6) + 30 + 6(10) = 58.33 + 30 + 60 = 148.33 cm, which is approximately 150 cm.
