class openquake.hazardlib.gsim.cauzzi_2014.CauzziEtAl2014

Implements GMPE developed by Carlo Cauzzi et al (2014) and published as C.Cauzzi, E. Faccioli, M. Vanini and A. Bianchini (2014) “Updated predictive equations for broadband (0.0 - 10.0 s) horizontal response spectra and peak ground motions, based on a global dataset of digital acceleration records”, Bulletin of Earthquake Engineering, In Press

Spectral acceleration (SA) values are obtained from displacement response spectrum (DSR) values (as provided by the original equations) using the following formula

SA = DSR * (2 * π / T) ** 2

COEFFS = <openquake.hazardlib.gsim.base.CoeffsTable object>

Coefficient table constructed from the electronic suplements of the original paper.

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Average horizontal'

Supported intensity measure component is the geometric mean of two horizontal components AVERAGE_HORIZONTAL,

DEFINED_FOR_INTENSITY_MEASURE_TYPES = set([<class 'openquake.hazardlib.imt.PGA'>, <class 'openquake.hazardlib.imt.PGV'>, <class 'openquake.hazardlib.imt.SA'>])

Supported intensity measure types are spectral acceleration, peak ground acceleration and peak ground velocity. The original paper provides coefficients for PGA and PGV, while SA is obtained from displacement response spectrum values. Coefficients for PGA are taken from the SA (0.01 s) spectral acceleration, as indicated in Page 11 (at the time of writing) of Cauzzi et al. (2014)

DEFINED_FOR_STANDARD_DEVIATION_TYPES = set(['Intra event', 'Inter event', 'Total'])

Supported standard deviation types are inter-event, intra-event and total

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Active Shallow Crust'

Supported tectonic region type is active shallow crust,

REQUIRES_DISTANCES = set(['rrup'])

Required distance measure is Rrup,

REQUIRES_RUPTURE_PARAMETERS = set(['rake', 'mag'])

Required rupture parameters are magnitude and rake

REQUIRES_SITES_PARAMETERS = set(['vs30'])

Required site parameter is only Vs30

See superclass method for spec of input and result values.

class openquake.hazardlib.gsim.cauzzi_2014.CauzziEtAl2014NoSOF

Returns the Cauzzi et al (GMPE) for the case when no style-of-faulting is input. This modifies both the expected ground motion as well as the inter-event (and thus total) standard deviations.

REQUIRES_RUPTURE_PARAMETERS = set(['mag'])

Required rupture parameters are magnitude

class openquake.hazardlib.gsim.cauzzi_2014.CauzziEtAl2014FixedVs30

Implements the Cauzzi et al (2014) model for the case in which the reference Vs30 in the site amplification term is fixed at 800 m/s

class openquake.hazardlib.gsim.cauzzi_2014.CauzziEtAl2014FixedVs30NoSOF

Implements the Cauzzi et al (2014) model for the case in which the reference Vs30 in the site amplification term is fixed at 800 m/s

class openquake.hazardlib.gsim.cauzzi_2014.CauzziEtAl2014Eurocode8

Implmements the Cauzzi et al. (2014) GMPE for the case in which the Eurocode 8 site classification is preferred

class openquake.hazardlib.gsim.cauzzi_2014.CauzziEtAl2014Eurocode8NoSOF

Implmements the Cauzzi et al. (2014) GMPE for the case in which the Eurocode 8 site classification is preferred and style of faulting is not specified.
