A spectrum analysis is one in which the results of a modal analysis are used with a known spectrum to calculate displacements and stresses in the model. It is mainly used in place of a time-history analysis to determine the response of structures to random or time-dependent loading conditions such as earthquakes, wind loads, ocean wave loads, jet engine thrust, rocket motor vibrations, and so on.
The following spectrum analysis topics are available:
- 6.1. Understanding Spectrum Analysis
- 6.2. Performing a Single-Point Response Spectrum (SPRS) Analysis
- 6.3. Example: Spectrum Analysis (GUI Method)
- 6.4. Example: Spectrum Analysis (Command or Batch Method)
- 6.5. Where to Find Other Examples
- 6.6. Performing a Random Vibration (PSD) Analysis
- 6.7. Performing a DDAM Spectrum Analysis
- 6.8. Performing a Multi-Point Response Spectrum (MPRS) Analysis
