Hi all,
I have a job in the works with tilt panel walls (basically a single storey big box) with a timber ply ceiling. I am happy to structurally use this ply ceiling as a diaphragm, yet am not sure if I can comply with the Building Code of Australia (BCA) regulations that stipulates the panels should not collapse outwards in the event of an internal fire, if I don't provide a steel trussed diaphragm at roof/ceiling level. Further to that point, would steel cross-ties be sufficient along with the ply diaphragm to satisfy the BCA, or must the steel be integral to the trussed diaphragm? Cantilevering the panels from the footing/slab on ground level is not a desirable option at the moment.
It would be appreciated to hear anyone comments or experiences.
Thanks
Toby
