openquake.hazardlib.gsim.akkar_2014.
AkkarEtAlRjb2014
[source]¶ Implements GMPE developed by S. Akkar, M. A. Sandikkaya, and J. J. Bommer as published in “Empirical GroundMotion Models for Point and Extended Source Crustal Earthquake Scenarios in Europe and the Middle East”, Bulletin of Earthquake Engineering (2014), 12(1): 359  387 The class implements the equations for JoynerBoore distance and based on manuscript provided by the original authors.

COEFFS
= <openquake.hazardlib.gsim.base.CoeffsTable object>¶ Coefficient table (from Table 3 and 4a, page 22) Table 4.a: Perioddependent regression coefficients of the RJB groundmotion model sigma is the ‘intraevent’ standard deviation, while tau is the ‘interevent’ standard deviation

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT
= 'Average horizontal'¶ The supported intensity measure component is ‘average horizontal’, see section ‘A New Generation of European GroundMotion Models’, page 8

DEFINED_FOR_INTENSITY_MEASURE_TYPES
= set([<class 'openquake.hazardlib.imt.SA'>, <class 'openquake.hazardlib.imt.PGA'>, <class 'openquake.hazardlib.imt.PGV'>])¶ The supported intensity measure types are PGA, PGV, and SA, see table 4.a, pages 2223

DEFINED_FOR_STANDARD_DEVIATION_TYPES
= set(['Total', 'Inter event', 'Intra event'])¶ The supported standard deviations are total, inter and intra event, see table 4.a, pages 2223

DEFINED_FOR_TECTONIC_REGION_TYPE
= 'Active Shallow Crust'¶ The supported tectonic region type is active shallow crust because the equations have been developed for “all seismically active regions bordering the Mediterranean Sea and extending to the Middle East”, see section ‘A New Generation of European GroundMotion Models’, page 4.

REQUIRES_DISTANCES
= set(['rjb'])¶ The required distance parameter is ‘JoynerBoore’ distance, because coefficients in table 4.a, pages 2223, are used.

REQUIRES_RUPTURE_PARAMETERS
= set(['rake', 'mag'])¶ The required rupture parameters are rake and magnitude, see equation 1, page 20.

REQUIRES_SITES_PARAMETERS
= set(['vs30'])¶ The required site parameter is vs30, see equation 1, page 20.

c1
= 6.75¶ c1 is the reference magnitude, fixed to 6.75Mw (which happens to be the same value used in Boore and Atkinson, 2008) see paragraph ‘Functional Form of Predictive Equations and Regressions’, page 21

get_mean_and_stddevs
(sites, rup, dists, imt, stddev_types)[source]¶ See
superclass method
for spec of input and result values.Implement equation 1, page 20.
