If you select more than one column and the pile/shaft cap type, the Combined Pile Footing Design screen displays, as shown below.

Data input is similar to the Isolated Pile/Shaft Cap Footing Design screen, as follows.

Start by inputting the footing size by selecting the footing from the Description menu (previously-defined under the Libraries | Footing Configuration option) and inputting the values in the textboxes.

Next, input the pile/shaft configuration information. Note that this section is only available for pile footings; that is, if you selected the pile/ shaft footing type on the Footing screen. Select the shape of the pile/ shaft from the Pile/Shaft Shape list, and input the values for the pile/shaft size and maximum pile capacity. Then click the Edit Pile button to activate the Edit: Pile Locations screen. Input the values and click OK when completed and return to the Combined Pile Footing Design screen.
