RIGRESP
RIGRESP, Option
, Method
, Val1
, Val2
Specifies the rigid response calculation.
Option
Flag to activate or deactivate the rigid response calculation:
1 (ON or YES)
—
Activate.
2 (OFF or NO)
—
Deactivate. This value is the default.
Method
Method used to calculate the rigid response:
GUPTA
—
Gupta method.
LINDLEY
—
Lindley-Yow method.
Val1
If
Method
= GUPTA,Val1
represents the frequency F1 in Hertz.If
Method
= LINDLEY,Val1
is the Zero Period Acceleration (ZPA). If a scale factor is defined (FACT in the SVTYP command), it is used to scale this valueVal2
If
Method
= GUPTA,Val2
represents the frequency F2 in Hertz.
Notes
This rigid response calculation is only valid for single-point response spectrum analysis (SPOPT, SPRS) and multiple-point response spectrum analysis (SPOPT, MPRS) with combination methods square root of sum of squares (SRSS), complete quadratic (CQC) or Rosenblueth (ROSE).
This command is also valid in PREP7.
