23.1.2 Effective Width of Flange.

In the absence of more accurate determination. The effective width of the flange may be taken as the following but in no case greater than the breadth of the web plus half the sum of the clear distances to the adjacent beams on either side.
a) For T-beams, B(eff) = (Lo/6)+bw+6Df.
Lo = Effective span length.
Bw = Width of rib.
Df = Depth of flange.

Least of the above means what?

Explain.

Makar said:   8 years ago
The width of flange means the t section above horizontal member and the flange is always less than 1/3 and distance.

Least of above means?

Ganesh said:   8 years ago
It should be l/12+bw+3Df.

EDDY said:   8 years ago
B is correct.

Hemant Sharma said:   8 years ago
1 Bf=Lo/6+bw+6df.

2 Centre to centre distance between adjacent slab,
Minimum of both of them.
So correct answer is B.
