SVTYP, KSV
, FACT
, KeyInterp
Defines the type of single-point response spectrum.
KSV
Response spectrum type:
0
—
Seismic velocity response spectrum loading (SV values interpreted as velocities with units of length/time).
1
—
Force response spectrum loading (SV values interpreted as force amplitude multipliers).
2
—
Seismic acceleration response spectrum loading (SV values interpreted as accelerations with units of length/time2).
3
—
Seismic displacement response spectrum loading (SV values interpreted as displacements with units of length).
FACT
Scale factor applied to spectrum values (defaults to 1.0). Values are scaled when the solution is initiated (SOLVE). Database values remain the same.
KeyInterp
Key to activate or deactivate the linear interpolation between input response spectrum points and input response spectrum curves:
0 (OFF or NO)
—
Deactivate linear and use logarithmic interpolation. This value is the default.
1 (ON or YES)
—
Activate linear interpolation.
