Composite Beam with High Axial Load

[FootNMouth]

I have a concentrically braced frame with 2 story X bracing. The braces take a considerable amount of compression under the gravity load cases. Likewise the brace beams are under large amount of tensile force. Can I still design the brace beams as being composite even with this large tensile force. My first thought is that I can not because it is similar to when the top flange of a cantilever is in tension, however in this situation the entire section could be in tension.

I would belive that unless reinforcing is present in the slab above the beam, the designing it non-composite is the right way to do it.
