Drop ceiling systems
and their fixtures (lights, signs, etc.) are typically suspended with tie wires
from the framing above. In seismic areas like California, they typically
add periodic diagonal tie wires in all four directions with occasional
compression elements to prevent uplift.
architectural details, it appears that the census is for the use of #12 wire
with a minimum of 4 turns in 1.5" for both the vertical tie wires and for the
diagonal sway wires.
I have heard a rumor
that #8 minimum wire is required. Which is correct?
What is the capacity
of a #12 wire with the 4 turns in 1.5"? What happens if the turns are
spread out over a greater distance? If more or less turns are
present? Is there any resources or gurus I can consult on
