Class CB_2003_AttenRel

java.lang.Object
  org.opensha.sha.imr.AbstractIMR
      org.opensha.sha.imr.AttenuationRelationship
          org.opensha.sha.imr.attenRelImpl.CB_2003_AttenRel

All Implemented Interfaces:: Serializable, Comparable<IntensityMeasureRelationship>, Named, XMLSaveable, IntensityMeasureRelationship, ScalarIMR

public class CB_2003_AttenRel
extends AttenuationRelationship
extends AttenuationRelationship

Title: CB_2003_AttenRel

Description: This implements the Attenuation Relationship developed by Campbell & Bozorgnia (2003), Bull. Seism. Soc. Am., vol 93, num 1, pp 314-331)

Supported Intensity-Measure Parameters:

pgaParam - Peak Ground Acceleration
saParam - Response Spectral Acceleration

Other Independent Parameters:

magParam - moment Magnitude
distanceSeisParam - closest distance to seismogenic part of fault
siteTypeParam - "Firm Soil", "Very Firm Soil", "Soft Rock", "Firm Rock", "Generic Soil", "Generic Rock", or "NEHRP BC"
fltTypeParam - Style of faulting
hangingWallParam - Hanging wall parameter
componentParam - Component of shaking
stdDevTypeParam - The type of standard deviation (mag or PGA dependent)

NOTE: The mean calculation for the site class "BC Boundary" is only approximate at 0.05- and 0.075-second periods (because "bv" is not available from BJF_1997 at those periods, so values were linearly interpolated between 0 and 0.1 seconds) and at 3- and 4-seconds ("bv" not available from BJF_1997 above 2 seconds, so value at 2-seconds was applied).

Constructor Detail

CB_2003_AttenRel

public CB_2003_AttenRel(ParameterChangeWarningListener listener)

No-Arg constructor. This initializes several ParameterList objects.

Method Detail

setFaultTypeFromRake

protected void setFaultTypeFromRake(double rake,
                                    double dip)
                             throws InvalidRangeException

Sets the style of faulting from the rake & dip angles (which come from the eqkRupture object). It's "Thrust" if 22.5=45 degrees, and "Other" if the rake is any other value.

Parameters:: rake - ave. rake of rupture (degrees); dip - ave. dip (degrees)
Throws:: InvalidRangeException - If not valid rake angle

setEqkRupture

public void setEqkRupture(EqkRupture eqkRupture)
                   throws InvalidRangeException

This sets the eqkRupture related parameters (magParam and fltTypeParam) based on the eqkRupture passed in. The internally held eqkRupture object is also set as that passed in. Warning constrains are ingored.

Specified by:: setEqkRupture in interface IntensityMeasureRelationship
Overrides:: setEqkRupture in class AbstractIMR

Parameters:: eqkRupture - The new eqkRupture value
Throws:: InvalidRangeException - thrown if rake is out of bounds

setSite

public void setSite(Site site)
             throws ParameterException

This sets the site-type and basin-depth parameters based on what is in the Site object passed in (the Site object must have these parameters in it). This also sets the internally held Site object as that passed in.

Specified by:: setSite in interface IntensityMeasureRelationship
Overrides:: setSite in class AbstractIMR

Parameters:: site - The new site object which contains the site-related parameters.
Throws:: ParameterException - Thrown if the Site object doesn't contain either of these parameters.

getName

public String getName()

get the name of this IMR

Specified by:: getName in interface Named
Specified by:: getName in interface IntensityMeasureRelationship
Overrides:: getName in class AbstractIMR

Returns:: the name of this IMR

getShortName

public String getShortName()

Returns the Short Name of each AttenuationRelationship

Returns:: String

setPropagationEffectParams

protected void setPropagationEffectParams()

This sets the two propagation-effect parameters (distanceSeisParam and hangingWallParam) based on the current site and eqkRupture. The hanging wall term is nonzero only if the dip is less than 70 degrees AND the fault is of type reverse or thrust. Point sources are give a zero value regardless of the dip and fault type. These specifications were conveyed to Ned Field by Ken Campbell in a series of emails.

Specified by:: setPropagationEffectParams in class AttenuationRelationship

updateCoefficients

protected void updateCoefficients()
                           throws ParameterException

This function determines which set of coefficients in the HashMap are to be used given the current intensityMeasure (im) Parameter. The lookup is done keyed on the name of the im, plus the period value if im.getName() == "SA" (seperated by "/"). SWR: I choose the name update instead of set, because set is so common to java bean fields, i.e. getters and setters, that set() usually implies passing in a new value to the java bean field. I prefer update or refresh to functions that change internal values internally

Throws:: ParameterException

getMean

public double getMean()
               throws IMRException

Calculates the mean of the exceedence probability distribution.

Returns:: The mean value
Throws:: IMRException

calcMean

protected double calcMean()
                   throws IMRException

This calulates the mean assuming the coefficients have already been assigned (this way PGA can be computed in getStdDev() without having to override the current im).

Returns:
Throws:: IMRException

getStdDev

public double getStdDev()
                 throws IMRException

Description copied from interface: ScalarIMR

This returns the standard deviation (stdDev) of the intensity-measure level for the current set of parameters.

Returns:: The stdDev value
Throws:: IMRException

setParamDefaults

public void setParamDefaults()

Description copied from interface: IntensityMeasureRelationship

This sets the defaults for all the parameters.

initIndependentParamLists

protected void initIndependentParamLists()

This creates the lists of independent parameters that the various dependent parameters (mean, standard deviation, exceedance probability, and IML at exceedance probability) depend upon. NOTE: these lists do not include anything about the intensity-measure parameters or any of thier internal independentParamaters.

initSiteParams

protected void initSiteParams()

Creates the Site-Type parameter and adds it to the siteParams list. Makes the parameters noneditable.

Specified by:: initSiteParams in class AttenuationRelationship

initEqkRuptureParams

protected void initEqkRuptureParams()

Creates the two Potential Earthquake parameters (magParam and fltTypeParam) and adds them to the eqkRuptureParams list. Makes the parameters noneditable.

Specified by:: initEqkRuptureParams in class AttenuationRelationship

initPropagationEffectParams

protected void initPropagationEffectParams()

Creates the Propagation Effect parameters and adds them to the propagationEffectParams list. Makes the parameters noneditable.

Specified by:: initPropagationEffectParams in class AttenuationRelationship

initSupportedIntensityMeasureParams

protected void initSupportedIntensityMeasureParams()

Creates the two supported IM parameters (PGA and SA), as well as the independenParameters of SA (periodParam and dampingParam) and adds them to the supportedIMParams list. Makes the parameters noneditable.

Specified by:: initSupportedIntensityMeasureParams in class AttenuationRelationship

initOtherParams

protected void initOtherParams()

Creates other Parameters that the mean or stdDev depends upon, such as the Component or StdDevType parameters.

Overrides:: initOtherParams in class AttenuationRelationship

initCoefficients

protected void initCoefficients()

This creates the hashtables of coefficients for the supported intensityMeasures (im). The key is the im parameter name, plus the period value for SA (separated by "/"). For example, the key for SA at 1.00 second period is "SA/1.00".

initHorzCoefficients

protected void initHorzCoefficients()

This initializes the horizontal-component coeffiecients. Note that the "bv" values at 0.05- and 0.075-second period were obtained by linearly interpolating those at 0 and 0.1 seconds (these come from BJF_1997, and are used to compute the mean for the "BC Boundary")

initVertCoefficients

protected void initVertCoefficients()

This initializes the Vertical component coeffiecients. Note that the "bv" values at 0.05- and 0.075-second period were obtained by linearly interpolating those at 0 and 0.1 seconds (these come from BJF_1997, and are used to compute the mean for the "BC Boundary")

getInfoURL

public URL getInfoURL()
               throws MalformedURLException

This provides a URL where more info on this model can be obtained

Specified by:: getInfoURL in interface IntensityMeasureRelationship
Overrides:: getInfoURL in class AbstractIMR

Returns:: the URL to the AttenuationRelationship document on the Web.
Throws:: MalformedURLException - if returned URL is not a valid URL.
