Piles are defined in the Edit Piles dialog and are assigned to pile caps using the Assign Pile Geometry command.

Pile definitions are given a label and effective diameter. For rectangular or other shaped piles the effective pile diameter will need to be calculated. In addition, the engineer should specify the compression capacity, tension capacity and shear capacity for the piles. Tension and shear values can be set to zero. Piles are assumed to have no flexural capacity. Piles that have been assigned to pile caps cannot be deleted.
