Fields

Modifier and Type	Field and Description
static Range<Double>	DAMPING_RATIO_RANGE The range of damping ratios supported by this model: [0.5..30.0].

Method Summary

Modifier and Type	Method and Description
ScalarGroundMotion	apply(ScalarGroundMotion sgm, GmmInput in, Imt imt, Gmm gmm) If the configured damping ratio equals 5.0% or SUPPORTED_GMMS does not contain the supplied gmm, this method returns the supplied ScalarGroundMotion, sgm.

Field Detail

DAMPING_RATIO_RANGE

public static final Range<Double> DAMPING_RATIO_RANGE

The range of damping ratios supported by this model: [0.5..30.0].

SUPPORTED_GMMS

public static final Set<Gmm> SUPPORTED_GMMS

The GMMs supported by this model. Currently the Rezaien et al. (2014) model only supports GMMs for active continental crust (i.e. the NGA-West1 and NGA-West2 models as implemented for the 2008 and 2014 NSHMs for the Conterminous U.S. This set is for external use and filtering prior to calling public methods of this class.

Method Detail

apply

public ScalarGroundMotion apply(ScalarGroundMotion sgm,
                                GmmInput in,
                                Imt imt,
                                Gmm gmm)

If the configured damping ratio equals 5.0% or SUPPORTED_GMMS does not contain the supplied gmm, this method returns the supplied ScalarGroundMotion, sgm.

Specified by:

apply in interface GmmPostProcessor

Parameters:

sgm - the ScalarGroundMotion to modify

in - the source-site parameterization

imt - the intensity measure type being considered

gmm - the ground motion model in use
