This paper shows an optimized model for rectangular pile caps, or footings, supported on a group of piles to obtain the minimum surface area in plant, supporting an axial load and two moments in the direction of the X and Y axis due to a column. This model assumes that the caps are perfectly rigid, and the piles are articulated at the junction of the caps with the piles; therefore, the piles transmit only vertical load. The methodology normally used to obtain the surface area of the caps is proposed in accordance to the distribution of the piles, taking the specifications set by the building codes into account. Also, five types of caps supported on a group formed by two, three, four, five and six piles are shown to demonstrate the accuracy of the model presented.

Palabras llave : Optimized model; rectangular pile caps or footings; minimum surface; group of piles.
