# Atkinson Boore 2003 Intensity Model

## Class Name

• RAtkinsonBoore2003IntensityModel

## Location in Objects Pane

• Models > Model > Hazard > Earthquake > Intensity > Atkinson Boore 2003 Intensity

## Model Description

### Model Form

• This model produces the spectral acceleration or the peak ground acceleration at specified locations for given magnitude and hypocentre location of several earthquake sources as input, based on the Atkinson-Boore (2003) attenuation relation.
• For more information, see Boore-Atkinson (2003)

• 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

• $${\varepsilon}$$ = Model error, typically a standard normal random variable

### Event Type

• Type of the earthquake event that can either be Interface or In-slab.

### Response Type

• Type of the response than can either be $${S_a}$$ or $${PGA}$$.

### Smoothness

• “Smoothed” option will smooth the kinks in the model and the “Original” option will use the model as it is.

### 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 the 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”.
