Column Height - Beam one side slab other
Column Height - Beam one side slab other
(OP)
This is a simple question but I cant find a clear answer in the codes we use:
If you have a concrete column supporting a slab, but also a downstand beam that ties into one face of the column at the top, can you use the column base to slab- or beam soffit as the column clear height?
In this case there is a 1.2m downstand beam. Can the column clear height for bending in the beam span direction be taken as column base to beam soffit and for bending in transverse direction from column base to slab soffit?

The BS defines clear height of a column, as used to calculate the effective height, as clear height between points of restraint. In this case I would think that the point where beam soffit ties into column gives restraint to the column in one direction. In the other direction (about the other axis) I would say the clear height is at slab soffit. Would this be an acceptable way to go about it?

I would consider the unbraced length to be to the bottom of the beam in the beam direction.
