bearing.phi_from_toe_bearing()

Friction angle whose toe bearing on sigma_v equals q_needed.

Usage

Source

bearing.phi_from_toe_bearing(
    q_needed,
    sigma_v,
    options,
)

Parameters

q_needed: float

Required unit toe resistance, ksf.

sigma_v: float

Vertical effective stress at the toe, ksf.

options: ModelOptions

Supplies the friction angle bounds and rigidity parameters.

Returns

phi: float

Friction angle, deg, held at a bound when the requirement lies outside the attainable range; NaN when q_needed is not finite.

reason: str

One of the reason codes in driven_pile.constants.
