Model Description

Model Form

• This model produces the spectral acceleration, peak ground acceleration, or peak ground velocity at specified locations for given magnitude and hypocenter location of several earthquake sources as input , based on the Campbell-Bozorgnia (2008) attenuation relation.
• Depth of each earthquake is predicted based on the magnitude.
• For more information, see Campbell-Bozorgnia (2008).

DDM Sensitivities

• No

Properties

Object Name

• Name of the object in Rt
• Allowable characters are upper-case and lower-case letters, numbers, and underscore (“_”).
• The name is unique and case-sensitive.

Display Output

• Determines whether the model is allowed to print messages to the Output Pane.

Magnitude List

• Magnitudes of various earthquake sources

Hypocentre Location List

• Hypocenter locations of earthquake sources, which automatically will yield the radius \({R}\) to the various output locations.

Epsilon Uncertainty List

• Intra-event model error, typically a standard normal random variable

Eta Uncertainty List

• Inter-event model error, typically a standard normal random variable

Fault Types

• Fault mechanism that can be either NormalSlip, StrikeSlip, or ReverseSlip.

Response Type

• Type of the response than can be either \({S_a}\), \({PGA}\), \({PGD}\), or \({PGV}\).

Period List

• List of the natural periods at which the intensity is evaluated

Structure Location List

• List of the locations where the intensity will be computed at them (the output will give as many intensity values as the locations provided here)

Shear Wave Velocity List

• List of the shear wave velocities at specified locations

Output

• Earthquake intensities (as many as the locations provided in the input).
• The output is an automatically generated generic response object, which takes the object name of the model plus “Response”.
