ABSTRACT
As presented in earlier chapters, a single pile or a group of piles under lateral load responds nonlinearly to applied load, and previous chapters have demonstrated the importance of incrementing loading to find the load that will cause collapse or cause excessive defection. Further, a number of case studies were presented to demonstrate that the models employed for pile and soil give answers that agree with experiment closely or within reasonable limits. Two areas of design need further discussion: (1) the broad range of factors that must
be considered; and (2) ensuring the validity of results from the computer code. These two topics will be addressed in the following paragraphs.
