Column Base as Fixed or Pinned
Column Base as Fixed or Pinned
(OP)
Let's say the bottom of your column member has a 4 bolt base plate connection to the foundation. Do you consider this as a fixed condition or a pinned condition.
At what point do you consider there is some rotation at the base plate for which a moment or fixed condition would not be appropriate?
Thanks for the help.

RE: Column Base as Fixed or Pinned
if the structure is much stiffer than the average bolted connection than I would consider it pinned.
(EG average portal frames, utility, building frames etc)
