pystrata.site.DampingCurve¶

class pystrata.site.DampingCurve(name='', strains=None, values=None, limits=None)[source]¶

Damping ratio curve.

Parameters:

name (str, optional) – used for identification
strains (numpy.ndarray, optional) – strains for each of the values [decimal].
values (numpy.ndarray, optional) – damping ratio values [decimal] corresponding to each strain.
limits (tuple, optional) – (min, max) limits for clipping interpolated values. Default: (0, 0.49)

__init__(name='', strains=None, values=None, limits=None)¶

Methods

`__init__`([name, strains, values, limits])
`from_published`(name, param)	Create a NonlinearCurve from published curves.

Attributes

`PARAMS`
`param`	Nonlinear parameter name ('mod_reduc' or 'damping').
`strains`	Strains [decimal].
`values`	Values of either shear-modulus reduction or damping ratio.
