Vehicle (lift) load on composite floor
Vehicle (lift) load on composite floor
(OP)
I have a 5 1/2" composite floor with 2", 20 ga. composite deck. My beams are spaced 7'6" oc.
The mason wants to use a 6100 lbs lift (weight of vehicle) to lift a pallet of masonry weighing 2800 lbs.
How do I check the capacity of my floor?

Make sure you give yourself enough time. This is a messy analysis. You'll have to check punching shear, bending on the composite slab; move the wheels to create maximum shear, check that; move the heaviest loaded wheels directly over the supporting beams and check them. Depending on the size of the lifting vehicle, you might get contributions from the back wheels on the beam analysis.
Don't assume anything! Just because the composite slab seems like the weak link doesn't mean that the beam connections, for example, are adequate.
