Models¶

Generic Interface¶

The interfaces for models have been simplified to use same parameter names and values where possible. Details of this interface are provided in GroundMotionModel.

class pygmm.model.Model(*args, **kwargs)[source]¶

__init__(*args, **kwargs)[source]¶: Initialize the model.

Summary of Methods

__init__(*args, **kwargs)

Initialize the model.

Attributes

`ABBREV`	Short name of the model
`LIMITS`	Limits of model applicability
`NAME`	Long name of the model
`PARAMS`	Model parameters

Mechanism¶

The following abbreviations are used for fault mechanism. Refer to each model for the specific definition of the mechanism.

Abbreviation	Name
U	Unspecified
SS	Strike-slip
NS	Normal slip
RS	Reverse slip

Specific Models¶

Each supported ground motion model inherits from Model, which provides the standard interface to access the calculated ground motion. The following models have been implemented.

`AbrahamsonGregorAddo2016`	Abrahamson, Gregor, and Addo (2016) ground motion moodel.
`AbrahamsonSilvaKamai2014`	Abrahamson, Silva, and Kamai (2014, []) model.
`AkkarSandikkayaBommer2014`	Akkar, Sandikkaya, & Bommer (2014, []) model.
`AtkinsonBoore2006`	Atkinson and Boore (2006, []) model.
`BooreStewartSeyhanAtkinson2014`	Boore, Stewart, Seyhan, and Atkinson (2014, []) model.
`Campbell2003`	Campbell (2003, []) model.
`CampbellBozorgnia2014`	Campbell and Bozorgnia (2014, []) model.
`ChiouYoungs2014`	Chiou and Youngs (2014, []) model.
`DerrasBardCotton2014`	Derras, Bard and Cotton (2014, []) model.
`HermkesKuehnRiggelsen2014`	Hermkes, Kuehn, Riggelsen (2014, []) model.
`Idriss2014`	Idriss (2014, []) model.
`PezeshkZandiehTavakoli2011`	Pezeshk, Zandieh, and Tavakoli (2011, []) model.
`TavakoliPezeshk05`	Tavakoli and Pezeshk (2005, []) model.

If you are interested in contributing another model to the collection please see Contributing.

Conditional Spectrum Models¶

Conditional spectra models are used to create an acceleration response spectrum conditioned on the response at one or multiple spectral periods. The The calc_cond_mean_spectrum() provides functions for developing conditional spectra based on one conditioning period, while the calc_cond_mean_spectrum_vector() uses the same correlation structure and permits conditioning on multiple periods.

`calc_correls`	Baker and Jayaram (2008, []) correlation model.
`calc_cond_mean_spectrum`	Conditional mean spectrum by Baker & Jayaram (2008, []).
`calc_cond_mean_spectrum_vector`	Kishida (2017, []) conditional spectrum.

Vertical-to-Horizontal (V/H) Models¶

Vertical-to-horizontal models are used to compute the vertical acceleration response spectrum from a horizontal response spectrum.
