In grillage foundations, distance between flanges of grillage beams, is kept A. 40 cm B. Equal to flange width C. Twice the flange width D. Maximum of (A), (B) and (C)

The correct answer is: B. Equal to flange width.

The flange width is the width of the beam that is perpendicular to the direction of the load. The distance between the flanges of grillage beams is kept equal to the flange width to ensure that the beams are able to carry the load evenly. If the distance between the flanges is too small, the beams may not be able to carry the load and may collapse. If the distance between the flanges is too large, the beams may be more susceptible to buckling.

Option A is incorrect because 40 cm is not necessarily the
