Time History Proportional Damp Data
Interpolated Damping Data Options for Time History Load Cases
Inputs
| Name | ID | Description | Type |
|---|---|---|---|
| Damping Type | T | Proportional Damping Type: (0=DAMP_BY_DIRECT_SPEC 1=DAMP_BY_PERIOD 2=DAMP_BY_FREQ) | Integer |
| Damp a | Da | The mass proportional damping coefficient. This item applies only when DampType = Direct Spec | Number |
| Damp b | Db | The stiffness proportional damping coefficient. This item applies only when DampType = Direct Spec. | Number |
| Damp f1 | Df1 | This is the period or the frequency (depending on the value of the DampType item) for point 1. This item applies only when DampType = Damp by Period/Freq | Number |
| Damp f2 | Df2 | This is the period or the frequency (depending on the value of the DampType item) for point 2. This item applies only when DampType = Damp by Period/Freq | Number |
| Damp d1 | Dd1 | This is the damping at point 1 (0 <= Dampd1 < 1). This item applies only when DampType = Damp by Period/Freq | Number |
| Damp d2 | Dd2 | This is the damping at point 2 (0 <= Dampd2 < 1). This item applies only when DampType = Damp by Period/Freq | Number |
Outputs
