The foundation project is of paramount importance in a structural design. The land carrying capacity and the ideal type of foundation for a building can be determined from surveys. Indirect foundation design can be made in caisson or pile caps and the choice also depends on the columns loads from structural design. This dissertation presents the design for the optimization problem of pile caps with application examples. The restrictions, will be those imposed by the parameters set by the ABNT NBR 6118: 2014 and the CEB FIP (1970), the spacing between the piles and the compression concrete strength (fck). A platform was developed in Matlab for the formulation of the problem, and its optimization will be obtained by the Interior Point Method. Comparative numerical examples show that when there is no geometry constraint, an optimal solution can be obtained by reducing the amount of piles and changing the geometry of the pile cap.
