generator on one way slab
(OP)
I have an existing one way slab concrete with 7x23" joists at 2'-3 o.c. with 3" slab. The client wants to install 2500 lb generator. I have done the analysis and it looks like the joist will be able to handle the load (not even close). Now, how would you mount this generator? I dont know how many bolts I need yet because I have not talked to the manuf. But I just want to know general idea what you usualy do on this situation. Would it be ok to put mount something on the 3" slab? Or do I need to tell them to only put the bolts on the top of the joist? (2'-3" apart). Since the generator is about 105" long, that means I can put 3 bolts each side. I am just worried that the skid plate already mounting holes so that we cant dictate where to put the generator.

Have you checked punching shear under the support points?
If the slab can take the load then I would tend to bolt through the slab, with a backing plate and then chemical anchor around the bolt in the slab. This gives good uplift resistance for any shaking effect.

Then you can bolt through the pad, between the joists, and through the 3" slab to attach the unit.
Be sure to include in your analysis some live load around the unit in addition to its weight.

kslee1000's suggestion to get the loading/skid info is good.
For further vibration control, an elastomeric mat between slab and housekeeping pad could also be considered.

Chamfer the corners all around. Minimum reinf. or WWF usually is used.
