Although I doubt if the weight of one or two people walking on a structural concrete slab is going to transmit through to the concrete pier causing vibration, a structural concrete slab would be a much better support for a shed and roll-off roof. Leave a 1/2" gap between the slab and pier, place foam backer rod and a good construction caulking sealent and you're ready to go.
