The study was conducted to establish a procedure for predicting pier deflections based on the theory of beams on elastic foundations and to establish a procedure for determining the parameters in the developed equation. Three sizes of expander plates were used in three trenches to determine the horizontal coefficient of subgrade reaction. Theory of elasticity was used in relating the coefficient to plate size and depth. A deflection relationship was proposed which describes pier deflection as a function of load, depth, and soil characteristics. Twenty piers of five types were tested with varying loads, depths, and diameters.
