Turnbuckle adjustment
Turnbuckle adjustment
(OP)
I am designing a hanger rod system for a running track suspended from the roof, and have included turnbuckles in the assembly for vertical adjustment. Is there any limitation in the amount of load that can be on a hanger rod when you adjust the turnbuckle? For example after the mezzanine concrete is in place and the roof joists have deflected I would like to have them adjust the elevation of the mezzanine by means of the turnbuckles.

If you don't want to upsize the rods, I suggest you specify sleeve nuts instead.
As a practical note, balconies supported by rods can be very bouncy. A classical example was the Russian Pavilion at Expo '67 in Montreal.
I suggest using pipes or tubes as your hanger and provide a shorter length to compensate for the calculated dead load deflection. You should also limit your live load deflection to L/480 to reduce vibrations related to walking or running.
