Response Spectra Generation Correlation Table
Description: Correlates output requests with frequency and damping values.
Format:
Example:
| Field | Definition | Type | Default |
|---|---|---|---|
| SID | Spectrum identification number. | Integer > 0 | Required |
| DAMPL | Identification number of a FREQ, FREQ1, or FREQ2 Bulk Data entry that specifies the list of damping values. | Integer > 0 | Required |
| FREQL | Identification number of a FREQ, FREQ1, FREQ2, FREQ3, or FREQ4 Bulk Data entry that specifies the list of frequencies. | Integer > 0 | Required |
| Gi | Grid point identification number where the response spectra will be calculated. | Integer > 0 | Required |
Remarks:
- This table is used in transient response solutions for the generation of response spectra.
- Damping values are in units of fraction of critical damping.
- Output of response spectra requires the use of the XYPLOT…SPECTRA(SID)/Gi…Case Control command, where the Gi is restricted to the grid points listed on the (SID) entry.
