DESCRIPTION:Load-displacement solutions for piles and shallow foundations 
 based on deformation fields and energy conservation\n\nAbstract:\nAn energ
 y approach for the prediction of nonlinear foundation behaviour will be pr
 esented. The approach is essentially a variant of the mobilisable strength
  design (MSD) method. However\, unlike the MSD method in which the displac
 ement field is constant\, in the presented approach it changes throughout 
 the loading sequence.  The formulation entails three main\nstages: [1] ass
 umption of admissible pattern functions from which displacement fields can
  be assembled\, [2] equating external work to internal work\, and [3] mini
 mization of internal work by variation of the displacement field using the
  different pattern functions. The approach is demonstrated on two problems
 : 1) a vertically loaded shallow foundation\, and 2) laterally loaded pile
 s.\n\nAnother variant of the MSD method\, entailing a simple nonlinear sca
 ling scheme of stress-strain curves for the solution of laterally loaded p
 iles\, will also be presented.\n\n
