0.1 L from the outer edge of column
0.1 L from the centre edge of column
Half the distance of projection
One-fourth the distance of projection
Answer is Right!
Answer is Wrong!
The correct answer is: C. Half the distance of projection.
Top bars are extended to the projecting parts of the combined footing of two columns L distance apart for a distance of half the distance of projection. This is done to provide additional support for the footing and to prevent it from cracking.
Option A is incorrect because it is not enough to provide adequate support for the footing. Option B is incorrect because it would not provide any additional support for the footing. Option D is incorrect because it would not be enough to provide adequate support for the footing.
