svtyp

Mapdl.svtyp(ksv='', fact='', keyinterp='', **kwargs)

Defines the type of single-point response spectrum.

APDL Command: SVTYP

Parameters:

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).

4 - PSD loading (SV values interpreted as acceleration2/(cycles/time), such as

(in/sec2)2/Hz (not g2/Hz)). (Not recommended)

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.

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.
