ASDIP FOUNDATION Structural Engineering Software

​Design Your Concrete Footings Quick and Confidently


ASDIP FOUNDATION is a structural engineering software utilized by engineers for design of concrete foundations, such as spread footings, strap footings, and combined footings, per the latest ACI 318 provisions.

ASDIP FOUNDATION substantially simplifies time-consuming calculations for structural engineering design. Load combinations per ASCE 7.

  • Quickly model your concrete footings with the simple and efficient graphical user interface.
  • Confidently optimize your design and comply with design Code provisions.
  • Impress clients and plan-checkers with eye-catching condensed or detailed reports.
  • Extensive documentation, solved examples, and blog posts to guide you throughout the software.
  • Use your valuable time wisely while ASDIP FOUNDATION does the hard work for you.
  • Much, much more...


After using this engineering software for a few months I believe it works very well for its intended purpose. ASDIP is very simple to use, is reasonably priced, and the calculation output is organized with a nice looking readable layout.

A combined footing is one that usually supports two columns. If a property line exists at or near the edge of an exterior column, an isolated footing would be placed eccentrically under this column and it would tend to tilt. Overturning of the exterior footing is prevented by supporting the two columns on a common footing.

The use of a combined footing may be justifiable under conditions where the distance between columns is short and the stability of an exterior isolated footing would be compromised. It is common practice to size the combined footing so that the resulting soil bearing pressure is uniform. To accomplish this, the footing shape is sometimes trapezoidal or rectangular, depending on the loads. A combined footing is usually analyzed as a beam in the longitudinal direction and as a footing in the transverse direction.

This software computes the soil bearing pressures induced by a cantilever footing under the action of vertical loads and bending moments, per the latest ACI design criteria. It designs the reinforcing steel, and checks the one-way and two-way shear stresses. In addition, the program generates the shear force and bending moment diagrams in order to design the reinforcement in the longitudinal direction. The concrete design is based on the Ultimate Strength Design Method of the ACI 318. Load combinations per the ASCE 7.


The input options are conveniently designed in tabbed pages. The required input data includes the footing and columns dimensions, the material properties, the allowable soil bearing pressure, and the acting service and factored loads. In addition, the program accepts a number of load cases, such as dead, live, snow, wind and seismic, to be combined internally. Alternatively, you can input a set of pre-combined loads.



The software checks the footing stability in overturning, sliding and uplift under the service combined loads, and performs the concrete design, which includes the one-way shear, punching shear and bending under the factored combined loads. In each case the controlling load combination is identified and reported.

For a quick overview of the design results click the “At a Glance” tab. A more detailed step-by-step calculations are available at the “Detailed” tab, which is updated with every new change. In addition, ASDIP Foundation uses a pre-formated colorful text-with-values output for easier identification of the problem areas. Use the Print Preview command to see a preview of the pre-formatted report on-screen, which includes the color graphics generated by the software.

ASDIP Foundation generates a graphical view of the designed footing and the resulting pressures and forces, as shown. The program also generates the moment and the shear diagrams for the controlling combination, as well as a view of the construction section and elevation with the reinforcement information.

I recently purchased all four of the ASDIP structural engineering software modules. After using this engineering software for a few months I believe it works very well for its intended purpose. ASDIP is very simple to use, is reasonably priced, and the calculation output is organized with a nice looking readable layout."
