    1The spacing "S" is the tributary load in the girder. It is found by adding the unsupported spans of the floor joists on each side that are supported by the girder and dividing by 2.

    2Figures under type of loading columns are the allowable girder span.

    Type A loading is for a girder supporting 1 floor and a roof.

    Type B loading is for a girder supporting 2 floors and a roof.

    Type C loading is for a girder supporting 3 floors and a roof.

    3Required size of column is based on girder support from 2 sides. Size of footing is based on allowable soil pressure of 2,000 pounds per square foot.

    4Schedule 40.

    5Footing thickness is based on the use of plain concrete with an ultimate compressive strength of not less than 2,000 pounds per square inch at 28 days. If approved, the footing thickness may be reduced based on an engineered design utilizing higher strength concrete and/or reinforcement.
