Stepped Columns with Single Axial Load
Stepped Columns with Single Axial Load
(OP)
Can anyone help me? I am trying to determine the effective Kl/r for a stepped steel column that has a single axial load. This column is not like a Crane Column with additional load at some mid-point. Most everything I have found requires the running of a program code. I am looking for a hand calculation if possible.

Can you clarify that, or post a sketch of the situation?

I'm not sure if it works or if the method used to make the charts converges for this situation.
It would be interesting to see it if does though.

Maybe this is the approach to use?
Not sure.

There are two ways I know of to obtain K-factors....one method is in Design Guide 7 and the other (the one I prefer) is in AIST tech. report 13.
Both yield very similar results and are quite simple.

The method yields results that are essentially identical.
AIST 13 is for the design of mill buildings.
I am not comfortable with copying the literature and posting it here.
Besides it has numerous pages of tables similar to APP B of DG7
