- Abstract
A method for analysing the cyclic behaviour of laterally loaded piles has been developed and applied to single vertical piles embedded in clay soils. The soil pile interaction model is bilinear- elasto- plastic and is based on subgrade reaction theory. Depending upon the pile soil characteristics and the magnitude and type of loading, the pile response may shakedown and stabilize to an elastic response, or continue to accumulate deflections and deteriorate until failure occurs. Comparisons are made between the theoretical behaviour and that measured in field tests. The analysis is used to simulate the increase in pile displacement, bending moments and gap development during each load cycle. The method also illustrates the different modes of failure that may occur as a result of cyclic loading. The comparisons demonstrate that the theory reproduces the observed characteristics of pile behaviour, and is capable of providing additional information which is often difficult to assess during field testing.
