GGU-LATPILE: At-rest earth pressure

The coefficient of at-rest earth pressure, k₀ , is obtained after FRANKE (Die Bautechnik 1974/No. 1) from:

The vertical load component resulting from wall friction is obtained from the tangent of the angle of wall friction. However, in accordance with the EAB, a minimum value of 0.5 · the horizontal component is assumed when the tangent of the angle of wall friction is < 0.5.
