capacity of a beam supporting plank 1

[athgoe]

When designing a steel beam to support hollow core plank floor, can this beam be designed as composite, or considering only 1" width is available at the stud location, should the beam be designed as non-composite.

I would not assume the beam to be composite. Also, the beam will be unbraced between the weld plates on the underside of the hollowcore plank (I usually assume 8' oc).

the UK do precast hollowcore plank floors composite with the supporting steel beam, and I'm sure they aren't the only one.
I would contact the manufacturer for advice on specific planks.
