Pressed pile force

Texas has migrated to 6 inch x 12 inch long pressed concrete cylinders or steel piers for slab foundation repair. The weight of the structure is used to press the pile. Does anyone know how much force is applied to a pile by the structure when it is installed? I realize a 1 story / 2 story etc will have variable potentials. A point of reference is appreciated.



If the house has trusses, then the gable end footing loads (dead load only) is about 350 lbs/ft and the two sides carrying the truss loads is about 700 lbs/ft. If the piles are spaced 6 foot apart then gable end would provide 2100 lbs and the other side would be 4200 lbs.
