Civil Engineering/pile foundation


Dear Sir

One direction shear wall has to be rest on pile foundation at its ends.

1. in case of two pile group , 3 pile group what should be the orientation of piles( in case of two piles it should be along the shear wall)

2). should there be a beam in between those two pile groups (between 2 ends) where shear wall to be started.
what is the principle of design this beam

Hi Priyantha,

1. This depends on whether there is out-of-plane moments in wall, but if not the 2-pile group should be parallel to wall.

2. Yes, you should have a ground beam between the pile caps, basically acting as a tie and possibly as a flange for the RC wall in case that is needed for bending action. (e.g. if the wall is short in height and long in span, so acts like a deep beam)
