Lateral loads for Mezzanine?
(OP)
Other than seismic, what other lateral loads would you consider for a mezzanine? The mezzanine will be used as a gym with stationery bicycles and running pads.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

The purpose is to ensure a robust structure and allow for practical difficulties such as lack of fit and out of plumb.
The difficulty with assuming unit loads applied horizontally is that the floor system has a relatively low surface area which will attract little load.

The intent is to ensure a minimum resistance to lateral drift in both braced and unbraced frames.
Whilst your mezzanine floor is hardy a multi-storey building, the notional horizontal force is a sound principle for ensuring the robustness of the structure.

"6.2.2 Minimum resistance
The structure shall have a minimum lateral resistance equivalent to 2.5 percent of (G + ?cQ) for each level, applied simultaneously at each level for a given direction.
The direction of application of the lateral load shall be that which will produce the most critical action effect in the element under consideration, except that the application of this load in more than one direction simultaneously need not be considered in the design of any
element."
G = dead load, Q = live load, ?c = combination factor (=0.4 normally, 0.6 for storage etc.)
