Civil Engineering - RCC Structures Design - Discussion

If we erect the steel for a column and footing, let's take 6 bars for the column. So we need to bend (90 °) these bars near the bottom and insert them into the footing. BUT BARS INSIDE THE FOOTING SHOULD BE MORE THAN 42 Times the diameter of the bar.

Let's consider our bar is 16mm, so we need to insert 42 *16= 672 mm into the footing, obviously, its counted from the bend or you can say the outer edge of the column.

And we have to do it with all 6 bars which we consider here.

Let's take an Isolated footing with the column on its top. Now provide reinforcement in it and extend it into footing up to 48d from the outer edge of the column. Hope this gonna help you guys.

Am not understand the question say as if you can please clear the question what it say please describe with pictures.

Doesn't the Ld value depends on the grade of steel.

Column reinforcement should be embeded Ld times inside the footing slab from the exterior edge of the column.

It is Leg distance of column reinforcement (vertical) which is extend 48 diameter to the footing from the outer edge of the column. Like shape of column vertical L. It is distance bottom part of L.

I am not understanding this. Can anyone explain me in brief?

l am not understanding this, Please describe the question with the figure.

It Normally taken 50D.

Yes, right @Archana.
