Steel columns in wood framed house
Steel columns in wood framed house
(OP)
If you have a steel column from the roof that goes all the way to the foundation, what do you do at each floor? Lets say the column is in the exterior wall, do you stop and start the top 2 plates to allow the column to go trough? How do you brace the column? I usually use the L of ceiling height (instead of roof to foundation) to calculate my column. How about if the column is not in a wall, what do you do when it hits the framed floor?

Your question is a bit general, and each case should be considered on its own, but as for general answers:
Assume the steel column is there only to support roof structure. It would be better to be continuous, with wall and/or floor framing connected to the column at the floor level to brace the column. Same answer if not in wall. Connect to joists and/or blocking.

If it is in the middle of the floor, provide solid blocking piece adjacent and through bolt column to blocking.

New wood structures shrink dramatically (versus steel or concrete) and can even "grow" when high humidity hits them.
Remember to allow for this or consider a wood column - if possible.

There is nothing in the code that I have seen that says you can't do that and my designs have passed many a code check.
Typically - use a bracket or lag through the I-beam into the column.
NOW - that said - what is the load??? Sometimes - wood just won't hack it - but most often it will. Six or seven studs with top steel plate is not unacceptable. Check buckling in both directions.
AND that column will shrink or grow about the same as the framed walls.
Good luck..
