Pile Cap Design and Analysis is a program for the interactive, windows-based, design and analysis of pile caps. This is not just another design program. While it can be used for initial designs, its real power lies in the interactive analysis of as-built pile groups and the initial design of configurations that are not covered in tabulated designs. Even if you initially use a tabulated design, you will still need a way to analyze the cap and pile reactions when the as-builts come in and are out of tolerance. If you've ever had to fix a P3 cap, you know that it is often necessary to add 2 piles to fix it. That can be iterative and computationally intensive by hand or with a DOS-based program where you must enter all pile coordinates by hand. The Professional Version of this program takes the work out of that exercise and you can get answers in moments. The interactive capability allows you to place piles in locations that align, or more closely align, the center of resistance to the center of load to minimize eccentricity. You can then simply read the new piles' coordinates and send them to the contractor. The design of the new cap is done at the same time. The Professional version takes you beyond the analysis of standard caps. In this version, you are able to add, delete and even temporarily ignore piles in a cap while you explore options. DOS-based programs and tables simply cannot give you that kind of flexibility.
Caps for 2 to 16 piles of any size, square or round, steel, concrete or timber of any capacity can be designed. These standard arrangements are pre-programmed so coordinates do not have to be typed in by hand. Just enter the number of piles and the program draws them in the standard layout and locates the cap edge. Optionally, if you only have axial loads the program will calculate the required number of piles based on the entered load. Spacing, edge distance, concrete strength, grout strength, cover, reinforcing, column size and more can all be varied in design. Caps can be designed for maximum pile capacity or for the calculated reactions. The standard 3" adverse tolerance can be included in the initial design and then excluded once the as-built locations are known. Cap thickness can be entered or the required thickness can be calculated. Once you have the as-builts from the field you can enter the 'real' loads and check the cap for the service condition. This can help you avoid an over-stressed condition if a pile(s) has been placed out of tolerance.
Once as-installed data from the field is received, piles can be precisely located either by absolute coordinates from the column center (grid line) or by individual deviations from theoretical pile locations. Piles can be moved on-screen with the mouse, by entering coordinates or with the arrow keys. The cap can then be recalculated with a single click. Design status is known immediately. Pile reactions are visually presented along with text indicators. Cap design is noted on-screen either as "OK", "NG" or "See Notes". Design problems are noted on-screen for rapid resolution. Reinforcement required in each direction, both top and/or bottom, is displayed on-screen. Drop-down boxes on-screen permit the user to select different rebar sizes in each direction.
Various Codes can be specified and basic checks are made for the Code selected. Use Metric or US Standard units. Convert between systems with a click.
Axial loads can be Compressive or Tensile. Moments about each or both axes can be entered. Service and Ultimate loads must both be entered, combinations are not calculated. Caps are designed for moments at the column faces and checks for minimum/maximum reinforcement ratios are made.
Both deep beam shear and conventional beam shear is checked. Pile punching shear, column punching shear (conventional and deep column punching shear) and corner shear are all checked.
Units may be mixed to more resemble hand calculations. That is, pile units can be in Tons, loads can be in Kips/Kip Feet and dimensional data may be in inches. So it is permissible to have loads in Kips and Feet but concrete strength in PSI. No need for annoying conversions to consistent units.
Designs can be saved, printed and opened as any Windows-based program can. Recent files are also provided for one-click opening. A help file is accessible by clicking the question mark icon or pressing 'F1'. Purchase of the full program also comes with example files.
We offer a free trial_version of the Basic Version by download. It is a limited-capacity version that does not expire. However, amongst other limitations, it is limited in the number of piles that may be analyzed. Results from the trial version cannot be saved or printed. Feel free to share it with all your friends. Be sure to check out the screen shot videos on the 'Examples' page.
The full version is ordered on-line but cannot be downloaded as it is dongle-protected. The dongle is for a single machine, not a network, at this time. Submit the filled-out form on-line and we will ship the software and hardware the next business day (international orders may require extra time).

I found the program invaluable for this as-built endeavor on my latest job. I’ve also been using it for all my pile cap designs for the last few years. Keep up the good work.
