Point Loads On Hollow Core
Point Loads On Hollow Core
(OP)
I need to put a small dunnage frame for some condensing units on the roof. The roof is 8" hollow core plank. Each leg has about 600 pound reaction. Are there any guide lines for point loads on hollow core plank?

What is going to be their location throughout the span? Close to bearing? Near mid-span?
Assuming (4) legs for a total of 2,400 LBS, depending on the proximity of the legs, the location throughout the precast span and considering the length of span, with this relatively "small" load, i would use "judgement" on whether the precast plank can support the load.
Consider the current existing loads, what will the shear be at existing precast bearing?
Do you have existing drawings specifying the psi of the plank? Do you know who the manufacturer / supplier of the plank is?
If i know the manufacturer / supplier / designer of the precast plank, i typically contact them and they tell me whether or not the plank can support the newly imposed load.
