Dear Friends ,
In the previous post , we worked out the RE BAR quantity in the Plinth beam B.6.
That was basically done to know how to extract various parameters from the RCC drawing .Later we worked out the total weight.
Refer the post here : RCC DRAWING
However , in the exercise , the Beam span of 4250 was already given. This dimension of 4250 mm was not given on the drawing but it was derived.
This post explains how that distance 4250 mm was derived from various other details.
So as usual , let us start from problem definition :
If you are wondering , how this 40 mm offset has been worked out , look at this sketch :
Now the picture is quite clear :
