Though not computer savy,,

I think tributary area has to be taken

Say if pile is of D m dia
The peripheral length = pi*D

If you are putting N springs along circum ference

And spaci ...

First of all let us think of one span

Deck Expanding -
Traffic moving from fixed to free bearing ,, Deck expanding
Fixed bearing force = B - T
Free Bearing Force = T

Enhanced shear capacity can be taken in above case as per IS 456 as enlightened by Er Rahul saheb.

Steel column s shed over Rcc column structure

I think it is better to go for pipe columns ( round/ square) having L/R same in two directions.
May be I section failing due to L/R in Lz dir.

Shear check - is a must

One way shear needs to be checked at mid section of two columns spacing distance,, in situation under discussion

To just summarize : (Statement already given in my pre ...

The soil under grade slab level is generally filled up, though little compacted, but has low bearing capacity compared to strata at foundation level.
Not a practice to take advantage of this in desi ...

By thinking logically :-

For Two way Shear to be checked at d/2 - if Columns are closer than d, then two way shear will overlap on this direction,, and There is need to check assuming Two columns ...

Respected N S Sir 's award and recognition in International Arenas is great ,,not only for himself, but for all Indians . His contributions to the field of Structural / Civil Engineering are beyond d ...

In this case :-
Please visit prime designer of Structure and share the actually provided at site.
He will suggest how much extra / Additional reinf in form of long bars as also insertion of rings ...

BUT IF SAID BEAM IS TRANSFER BEAM CARRYING ANY COLUMN LOAD OR MAIN BEAM CARRYING HEAVY POINT LOAD,, SUCH SUGGESTIONS SHALL NOT WORK .
