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:

  1. This table is used in transient response solutions for the generation of response spectra.
  2. Damping values are in units of fraction of critical damping.
  3. 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.
