✦ Synopsis

Most laterally loaded piles are flexible in the sense that they are not deformed over their entire lengths. Instead, pile deflections become negligible below an 'active pile length' L a : This L a is an important parameter that governs the overall behavior of a rigidly capped pile group. In the present approach, piles closely grouped together beneath a superstructure are viewed as a single equivalent upright beam whose stiffness matrix determines L a : This idea is verified for different cases of pile spacing, and is further extended for nonlinear behavior of soils surrounding grouped piles.
