SVTYP

SVTYP

SVTYP, KSV, FACT, KeyInterp
Defines the type of single-point response spectrum.

SOLUTION: Spectrum Options

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.

Command Default

Seismic velocity response spectrum.

Notes

Defines the type of single-point response spectrum [SPOPT]. The seismic excitation direction is defined with the SED command.

This command is also valid in PREP7.
