## Using MathCAD to find point of zero shear

(OP)

I'm trying to set up an equation in MathCAD to find the point of zero shear in a sheet pile wall. It returns an imaginary number. If you look on step 5 of the attached pdf it returns an answer of y-12.87ft when reduced to a workable quadratic equation. I'm trying to skip this step and solve for y. Does anyone have any suggestions? Thanks.

The cantilever sheet pile analysis in the Pile Buck Steel Sheet Piling Design Manual includes a "pivot point", below which the passive pressure reverses to the active side of the sheet. Your formulas don't seem to reflect a pressure reversal and result in a less consevative depth of embedment.
