Usage

Source

formulas.danish_capacity(
    bpf,
    stroke,
    ram_weight,
    pile,
    c1=0.45,
    c2=0.0,
)

Parameters

bpf: array_like

Blows per foot.

stroke: array_like

Hammer stroke, ft.

ram_weight: float

Ram weight, kips.

pile: Pile

Pile geometry and modulus.

c1: float = 0.45

Multiplicative and additive (kips) recalibration coefficients.

c2: float = 0.45

Multiplicative and additive (kips) recalibration coefficients.

Returns

ndarray

c1 * W h / (s + s0) + c2, kips, with the set per blow s = 1 / bpf ft.
