pygmm.akkar_sandikkaya_bommer_2014.AkkarSandikkayaBommer2014

class pygmm.akkar_sandikkaya_bommer_2014.AkkarSandikkayaBommer2014(scenario)[source]

Akkar, Sandikkaya, & Bommer (2014, [Akkar et al., 2014]) model.

The model is specified for three different distance metrics. However, the implementation uses only one distance metric. They are used in the following order:

  1. dist_jb

  2. dist_hyp

  3. dist_epi

This order was selected based on evaluation of the total standard deviation. To compute the response for differing metrics, call the model multiple times with different keywords.

Parameters:

scenario (pygmm.model.Scenario) – earthquake scenario

NAME = 'Akkar, Sandikkaya, & Bommer (2014)'

Long name of the model

ABBREV = 'ASB14'

Short name of the model

V_REF = 750.0

Return type:

np.ndarray

interp_spec_accels(periods, kind='linear')

Interpolate the spectral acceleration.

Interpolation of the spectral acceleration is done in natural log space.

Parameters:

  • periods (array_like) – spectral periods to interpolate the response.

  • kind (str, optional) – see scipy.interpolate.interp1d() for description of kind. Options include: ‘linear’ (default), ‘nearest’, ‘zero’, ‘slinear’, ‘quadratic’, and ‘cubic’

Returns:

spec_accels – interpolated spectral accelerations

Return type:
