zone.hysteretic

Syntax

f = zone.hysteretic(z,s)

zone.hysteretic(z,s) = f

Get/set the hysteretic damping parameter s in zone z. s can have the following possible values: c0, c1, c2, c3, modfac, model, e1, e2, e3, e4, e5, and e6.

c0, c1, c2, and c3 return/set the first through fourth parameters of the hysteretic model.

model returns/sets the hysteretic model identification number, where 1 = Default model, 2 = off, 3 = Sig3 model, 4 = Sig4 model, and 5 = Hardin model.

modfac returns/sets the current reduction factor.

e1 through e6 return/set strain components γ₁ … γ₆. See Hysteretic damping for more details.

Returns:

f - the value of the hysteretic damping value

Arguments:

z - a pointer to a zone

s - the name of the value to retrieve from the zone
