column unbraced height
column unbraced height
(OP)
I have a project where a column pokes through a concrete floor(concrete over steel deck - 5.5 total thickness). It will have the concrete floor all around it. Does this qualify as a brace point ? The floor to floor height is 15' and the total height of column is 29'. Is the unbraced length 15' or 29'?

We had the columns moved so that they do not poke through the floor.
In an extension to my question,for an exterior column, that has beams coming on both sides reducing the effective length in x-x direction, will concrete over steel deck brace it in the y-y direction. Is it better to have a joist framing into the column instead?
I had designed the columns to go full height in the y-y direction and my coworker is telling me it is overdesigned. He has always designed columns by assuming them braced by the concrete deck.

I would not rely on concrete bearing along for the nodal brace.
