Tie beam to pile caps
Tie beam to pile caps
(OP)
Hi
It is the usual practice in Middle East that pile caps are tied to the adjacent pile by means of tie beams. Some designers provided this only to single pile and two pile groups others providing this to almost all the pile cap?. For single pile, two tie beams in perpendicular direction and two pile group in their least dimension. What is the purpose of this tie beam?It is not mentioned in any of the design book I read!!! Is it part of seismic design? Could anyone suggest any link to any publication on this? or good design book?
Thanks
Regards

RE: Tie beam to pile caps
In a pile cap with two piles, the moment in the plane containing the two piles is resited by the push-pull on the two piles.
The other direction has no such capacity. The tie beam between the two adjacent pile caps in that direction carries the moment and converts it into the push-pull between the piles of the two pile caps.
The tie beam shall hence be desiged to carry the algebraic sum of the moments from both the columns in the direction, transferred at its ends.
