Column to Footing Reinforcement
Column to Footing Reinforcement
(OP)
I was just reading through some old standards from another company. It says that where the vertical reinforcement from the column meets the footing, the 90° bend shall be "near the bottom of the foundation with the free end of the bars oriented towards the center of the column"
Why would they not be oriented towards the outside of the footing?
Why would they not be oriented towards the outside of the footing?

In addition to the ACI definitional difference, I'm also considering the conceptual difference between a high moment column vs a low moment pedestal.

Regarding some of the structural elements in the reference that slickdeals' posted, are those things constructable? Particularly the forest of rebar shown in the pictures on pages 3 and 11?
And if that's what's required is it time to return to encasing hot-rolled steel shapes in concrete as was often done many years ago? That would seem to be easier to build than what's shown.
Any thoughts or comments?

Carefully planned, congested beam-column joints (Page 3) and core coupling beams (Page 11) are constructable, but they require care and a bit of sophistication. They also require well qualified inspection. Coupling beams not being constructed correctly is the primary reason for the impending demolition of the partly completed Harmon Tower in Las Vegas.

Not sure that there is a case to be made for concrete encased structural steel construction.

I found the second one on progressive collapse...what else it out there?
