Axial Stiffness (Empirical According to Tschuchnigg; with Inserted Recommended Values)

Empirical determination of the axial stiffness according to Franz Tschuchnigg (Tschuchnigg, F. (2012). 3D Finite Element Modelling of Deep Foundations Employing an Embedded Pile Formulation. Thesis. Technical University of Graz.) with additional recommended adjustment factor for implementation in RFEM. Solution with inserted recommended values.
