Rigid or Pinned Column Base Connection
Rigid or Pinned Column Base Connection
(OP)
I have a shear wall with concrete columns in the foundation walls and steel columns above. The question I have is at the steel column base plate where it meets the the top of the concrete column. Is that transition between the 4 anchor bolts considered a fixed end or pinned condition for the design of the 10 foot high concrete column ??

Thanks for the quick response. Do the 4 anchor bolts I have qualify for a certain percentage of fixity??
RE: Rigid or Pinned Column Base Connection
I would either assume it totally pinned or totally fixed and go from there. For the upper steel column design, the pinned condition will give you (usually) a more conservative design. For the anchors, a fixed condition assumption would give you a more conservative bolt design.
Hope that answers your question.

Assume a pinned connection.
What "hinge" are you talking about in a 10 foot high reinforced concrete column poured with a 12 inch concrete foundation wall??
