ASDIP FOUNDATION is a structural engineering software for design of concrete footings. It includes the design of spread footings based on the latest ACI provisions. Following is a graphical overview of the required design steps, with annotated screenshots of the software.

Enter the footing dimensions in plan and elevation view.

Specify the soil cover and the water table depth.

Click on the Column tab and specify the column dimensions.

The column can be offset in both directions.

If column is a short pedestal, loads will be applied at top of pedestal.

At-a-Glance tab shows summary of results, organized by topic.

Select either single pre-combined load, or a set of load cases.

If pre-combined, specify service and factored loads.

Specify the load combinations code, either ASCE 7-05 or 10.

Enter the applied loads. Load cases are D, L, Lr, S, W, and E.

Condensed tab shows more detailed results, organized by topic.

Specify material properties for footing and column.

Enter the allowable gross soil bearing pressure.

Detailed tab shows fully detailed results, with exposed formulas and Code references.

Specify soil friction coefficient for sliding resistance.

Specify the soil cover and concrete density.

Results show the controlling load combination at each stage.

Enter bar sizes for footing and column.

Specify number of rebars for footing and column.

Specify the direction of the outer bars.

Graph tab shows bearing diagram and values at corners.

Software shows the zero line for partial bearing.

Shear tab shows the shear values at the effective distance in both directions.

Flexure tab shows the moments at the effective distance in both directions.

Software shows the controlling combination for each condition.

Double check input and output.

Column tab shows the biaxial interaction diagram at the controlling angle.

Interaction diagram includes the actual load for easier comparison.

Software shows the controlling combination for the interaction diagram.

Software generates scaled sketch of the designed footing showing the reinforcement.
