Concrete Pier Integral with Concrete Wall
Concrete Pier Integral with Concrete Wall
(OP)
See the attached sketch.
I've got a wall that is very thick (20" thick) as it retains soil as a cantilevered retaining wall. The wall also supports steel columns. When the wall supports steel columns, I have "bump outs" to make room to support the column baseplates, anchorbolts, etc.
That said, I don't need the column horizontal closed ties to extend all the way across the wall thickness....but...I was wondering if you guys add lateral ties (per my sketch) to link the tensile face wall reinforcing on the back side with the vertical and cage reinforcing of the monolithic cast pier?
Something about the pier cage extending 1/2 way thru the wall thickness keeps making me look at it. But then again, the vertical column reinforcing is well within the thickness of the wall and seems to be fine as detailed.
What do you guys think? Is there any reason to link these vertical bars....or is that idea just a waste of time, money, and material?

Marinaman, if there was a horizontal thrust from the column pushing in the same direction as the retained soil and the retaining wall was used to resolve that thrust then I could imagine a need to tie those bars together in some manner. Otherwise I do not.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

The column only has vertical force, no thrust or lateral force is imposed onto the wall by the steel column.
