Bldg design for 4 stories. 1 was built. Can I rotate colmn. on 2nd?
Bldg design for 4 stories. 1 was built. Can I rotate colmn. on 2nd?
(OP)
Sorry for the short title as it is limited in Number of Characters.
I do some building design on the side, here is the situation:
* According to the design plans, the building was built for 4 stories (1+3).
* I'm designing the second floor right now, however, I'd like to rotate some of the columns from the Main floor
* Actual floor plan and proposed second can be found under http://97.107.136.148/plan_1_and_2.pdf The columns, I'd like to rotate are the ones within the zigzag circle. On the plan is the beam layout as well
Is this possible? Any other solutions I can look into?
cheers, and thanks in advance

Simple answer: maybe. Get a Structural engineer involved and tell the owner it will cost money to change it.

If I was the engineer and I got asked by anyone but the client, I would tell them where to go. Probably still would tell the client the same thing.

Can you provide more information on the structure.

Example: Usually, columns are two stories high, geting smaller at every other floor. The "usual" columns penetrate the floors, and are connected (spliced) to the next column higher about 24 - 36 inches above floor level.
So, if you want to rotate the column for some reason, you can't really rotate at the splice point since the lower and upper webs and flanges won't line up, but you have to do it where the connection won't stick out into the usable working areas of the building. So I'd think you could cut off the column coming up from the 2nd floor near the floor level of the third floor (below the concrete), then weld a heavy pair of plates in position to carry the forces through the joint, then continue up to the next splice point with the upper column rotated from the lower.
Where is my thinking wrong? Expensive, true, but is it wrong structurally?

We do not have enough information on this forum to give an accurate answer, only the original designer is able to do that.

But I agree that we don't have enough information to provide an accurate answer. It must be assessed properly by a local engineer.

Can you contact the original engineer... should be a simple fix.
