unbraced height of a column

unbraced height of a column

unbraced height of a column

(OP)
Hello,

I am checking a column which is being braced by a beam and a slab from the 2 sides. At the foundation level, it is supported on a raft foundation and is being braced by a retaining wall from the other side as per the attached sketch.
My question is regarding the unbraced height of the column. In the strong axis and based on the attached configuration, it is clear that the unbraced height is reduced due to the beam and the wall (lu = 2.2m). However, in the weak axis, i vote for an unbraced height of 3.2m.

your thoughts ??

thank you

RE: unbraced height of a column

I think that's a reasonable set of assumptions assumptions geo321.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
