A non-linear analysis of lateral loading behavior of single piles, in which the soil is described by its undrained shear strength, forms the basis of the design method. The constraints are the bending moment in the reinforced concrete section and the lateral deflection of the pile head. An analysis of pile cracking is carried out in order to ascertain its effects on flexural rigidity and load capacity under working load conditions. The results of the analyses, which encompass a broad range of the parameters most commonly encountered in practice, are presented in a number of design charts. These show that soil strength is the major determinant of the design and, in consequence, some simple equations have been developed for preliminary design purposes based only on this parameter. These also show that deflection constraints are hardly ever relevant to normal civil engineering practice unless the soils are particularly weak.
