Abstract:Several methods of analysis and design of piles under lateral loading are in use. Presumptive values that suggest allowable loads, but very conservative ones, are included in some manuals of practice. Batter piles may be employed with an assumption, not entirely correct, that no lateral load is taken by vertical piles. Several rational methods, in which the equations of mechanics are satisfied, have been proposed. The methods of Broms and of Poulos and his coworkers are reviewed. The rational method utilizes different equations to solve the governing differential equation along with the use of nonlinear curves to describe the soil response. Curves showing soil resistance p as a function of pile deflection y have been recommended for several types of soil and pile loading. Case studies are presented where results from analysis are compared with those from experiment. Design recommendations are made and needed research is outlined.
