When forces in foundation piles are calculated according to classic theory, thefoundation are assumed to be infinitely rigid which means that the foundation will notbend. High buildings need their whole width to be stable and use the ground floorwall as a foundation. But when, for example windows are needed in the ground floorwall, the stiffness of the foundation decreases which change the forces in the piles. Inthis report the difference of pile forces versus classic theory has been analyzed, and ifpile forces can be calculated as in classic theory. Further on, the effects of the wallmovement were analysed and how the buildings crack safety would be affected by themovement at the ground floor. From conclusions of the results, it seems that we arenot able to calculate the forces i the piles with classic theory when openings havebeen made in the ground floor wall. Instead we need a program like FEM-Design tocalculate these pile forces. Calculation with FEM-Design also gives the movement andthe internal forces of the building which can be useful in further design.
