DTI, SPECSEL

Response Spectra Input Correlation Table

Description: Correlates spectra lines specified on TABLED1 entries with damping values.

Format:

Example:

Field Definition Type Default
SID Spectrum identification number. Integer > 0 Required
TYPE Spectrum type, one of the following character variables: A, V, or D. See Remark 3. Character Required
TIDi TABLED1 entry identification number. Integer > 0 Required
DAMPi Damping value assigned to TIDi. Real Required

Remarks:

  1. The SID is the spectrum identification number of the spectrum defined by this entry. It is referenced on DLOAD Bulk Data entries that are selected in the Case Control Section using the DLOAD Case Control command.
  2. The TIDi, DAMPi pairs list the TABLED1 entry, which defines a line of the spectrum and the damping value assigned to it. The damping value is in the units of fraction of critical damping.
  3. The symbols (A for acceleration, V for velocity, and D for displacement) define the spectrum type.
