ests of lateral load capacities of slender steel piles

tests of lateral load capacities of slender steel piles
is anyone aware of any test data on the lateral capacity of relatively narrow (4" dia) steel repair piles?  i am trying to esstimate lateral resistance (if any) of existing "push" piles that were hydraulically driven vertically as part of foundation repairs.   
the completed piles are 35'+-long.  the shafts were installed in 4' long, pressure fitted nesting sections, and attached with brackets to the exist'g concrete foundations. the pile section is therefore typically not continuous and it does not seem reasonable to assume any bending resistance in the pile.
the surrounding soil may provide resistance to movement of the upper portion of the pile, but i think the small pile diameter must rule out typical methods used to estimate resistance.   has anyone any experience with this question?
any test data out there?
