QUESTION: How the program is calculating the Pile Reaction when the user selects " Cap as continuous Beam" or "Piles integral with Cap" options under Frame Analysis Method ?


When the user selects "Cap as continuous Beam" or "Piles Integral with cap" option under Frame Analysis method , In the analysis TAB the program performs Continuous Beam Analysis and Frame Analysis respectively and shows the reactions at difference Nodes.

When the user clicks on Pile Reaction TAB,internally the program calculates the CG of the Pile group and then the forces and moments are transferred to the centroid of the pile group and then forces are distributed to the piles based on equation shown in the attached screenshot. That's the reason the user sees 2 different values , one in Analysis TAB and one in Pile reaction TAB.
