ResponseSpectrum2D, ResponseSpectrum3D
Create a response spectrum 2D or 3D data set. A response spectrum analysis is a modal-based method for estimating the structural response to a transient, nondeterministic event. Typical applications are dimensioning against earthquakes and shocks.
Syntax
model.result().dataset().create(<dtag>,"ResponseSpectrum2D");
model.result().dataset().create(<dtag>,"ResponseSpectrum3D");
model.result().dataset(<dtag>).set(property, <value>);
Description
model.result().dataset().create(<dtag>,"ResponseSpectrum2D") creates a 2D response spectrum data set feature named <dtag>.
model.result().dataset().create(<dtag>,"ResponseSpectrum3D") creates a 3D response spectrum data set feature named <dtag>.
The input to a response spectrum is the results from an eigenfrequency computation.
The following properties are available for ResponseSpectrum2D and ResponseSpectrum3D:
Use absolute value for coupling terms, when modecomb is cqc, grouping, or tenpercent.
Augment with rigid response, when spatialcomb is cqc3 or srss3 (3D only).
none | data set name
Mass correction when rigidmodes is gupta: none or missing mass method.
staticzpa | missingmass | none
Mass correction when rigidmodes is lindleyyow: none, missing mass method, or static ZPA method.
cqc | abssum | srss | doublesum | grouping | tenpercent
none | function name
Relative damping when modecomb is cqc or doublesum.
lindleyyow | gupta | none
Secondary horizontal spectrum scale factor, when spatialcomb is cqc3 or srss3 (3D only).
none | function name
srss | percent | cqc3 | srss3
frequency | periodtime
pseudoacc | displacement | pseudovel
none | function name
Zero period acceleration frequency (when rigidmodes is not none). Available when spatialcomb is srss or percent.
