Abstract. The latest version of ASABE‘s shallow post and pier foundation design standard (ANSI/ASAE EP486.2) contains new procedures for determining the ultimate bearing, uplift and lateral strength capacities of the foundations. Presented in this paper are the theories and assumptions inherent in development of equations and methods for determining lateral movement and the ultimate lateral strength capacity of embedded piers and posts. Also presented are design examples and recommendations for adjustments to the recently completed standard.
