# Simple Damage Curve Model

## Class Name

• RSimpleDamageCurveModel

## Location in Objects Pane

• Models > Model > Consequence > Economic > Simple Damage Curve

## Model Description

### Model Form

• Sine curve from $${\theta_1}$$ to $${\theta_2}$$
• $$\eta = {1 \over 2} \cdot \left( {\sin \left( {{\pi \over {\varepsilon \cdot {I_{{\rm{max}}}} - {I_{{\rm{min}}}}}}\left( {I - {I_{{\rm{min}}}}} \right) - {\pi \over 2}} \right) + 1} \right)$$

• 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”.
