GGU-LATPILE: General
GGU-LATPILE solves the differential equation for an elastically embedded pile using the given boundary conditions.
EJ · w'''' + kS · b · w = q
with
E = Young's modulus
J = moment of inertia
w = pile displacement
kS = subgrade reaction modulus
b = pile width
q = load
The solution is determined numerically using the so-called finite element method.
Action boundary conditions at the pile head can be defined (see menu item "Editor 1/System input"). At the pile toe, boundary conditions are generally:
Moment = 0.0,
Shear force = 0.0,
Vertical displacement = 0.0.
If you want to define a moment restraint at the pile head, select the "Editor 2/Displacement boundary conditions" menu item and enter this condition directly below the pile head:
Proceed in a similar manner if, for example, you want to set horizontal displacement to zero (0).
