Drilled Pier Supported Shear Wall
Drilled Pier Supported Shear Wall
(OP)
There has been much debate in our office regarding the following scenario (see attachment). A shear wall supported on a grade beam supported by three drilled piers one at each end and one in the middle. The only loads resisting overturning are the uniform weight of the wall and concentrated beam loads at every level at mid length of the wall. The question is to what degree do the concentrated loads help resisting uplift in the outer drilled piers if the loads are centered over the center pier? Any thoughts are appreciated. Thanks

Teguci, in this particular instance it is required to resist the large lateral loads. Two piers are not enough.

tbone what I meant by my previous response is that the vertical loads will be distributed between all three piers and the moment will be resisted by the outer piers.

ron9876, I do agree with both your posts. But as far as the vertical load distribution to the three piers, what % each would get is the main question.
Thank you all for your continued input.

The contribution of the IT beams to the shear walls is why I like to place the shearwalls on the interior bays. For turning bays, openings in the shearwalls can help alleviate site line issues.

Teguci, I can tell we design similar structures. I agree and I also prefer to have the shear walls on the interior bays to get the extra dead load contribution. However we are always fighting the architects to get this.
Thanks again, I appreciate your valuable input.
