    Introduction This manual contains solved examples that were used to validate SoFA v.1.1.

    For an advanced description of the algorithms and formulas used, consult the analytical users manual.

    If you discover what you think is a bug, report it here. Please try to include all SoFA reports.

    !

    All loads considered act at the base of the footing and NOT at the theoretical

    point of column fixity (for more information check out the analytical users'

    manual).

    SoFA does NOT calculate the footing self weight .
