The IBC or UBC have diagrams that explain this as well as the methods of analysis
The sail area is calculated, a force equal to pounds/sq ft is derived from wind speed in your area. This times the surface area is the load on the structure.
Structure self weight is used to determine the hold-downs to the foundation on that particular face.
Roof holddowns are determined by the uplift force from the overhang, and straps are installed to keep the roof from ripping off.

It might help to think of the side of a building as a giant sail. It presents a large face to the wind which means a lot of force is applied laterally to the base of the building. The surface area of a building as a percentage of structural mass is one indicator used to evaluate the effects of wind loading.

wind loading is not mass dependent but its a factor of side area of the structure and the wind speed but finally it affects the structure as an earthqauke and u have to compare which controls

the significance is such the you design a building that won't fall over from the blowing wind.
