struct.pile.normal.disp

Syntax

f := struct.pile.normal.disp(p,iend)

Get the displacement in the coupling normal spring at end iend ∈ {1, 2} of the pile element. Sign convention for normal spring is positive/negative, indicating separation/overlap.

Returns:

f - the normal coupling spring stiffness of the element

Arguments:

p - a pointer to a pile element

iend - end number of the pile element, iend ∈ {1, 2}
