Model Description

Model Form

• Sine curve that gradually increases a damage factor from 0 at the minimum intensity, \({I_{{\rm{min}}}}\), to 1 at the maximum intensity, \({I_{{\rm{max}}}}\), as follows:
$$\eta = {1 \over 2} \cdot \left( {\sin \left( {{\pi \over {\varepsilon \cdot {I_{{\rm{max}}}} - {I_{{\rm{min}}}}}}\left( {I - {I_{{\rm{min}}}}} \right) - {\pi \over 2}} \right) + 1} \right)$$

DDM sensitivities

• Yes

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

• Indicates whether the model is allowed to print messages to the Output Pane

Intensity

• \({I}\) = Intensity

Min Intensity

• \({I _ {\min}}\) = Intensity at which the damage factor exceeds 0.0

Max Intensity

• \({I _ {\max}}\) = Intensity at which the damage factor reaches 1.0

Epsilon

• \({\varepsilon}\) = Multiplicative model error

Output

• \({\eta}\) = Damage ratio
• The output is an automatically generated generic response object, which takes the object name of the model plus “Response”.
