Response Spectrum
This tool is used to define the response spectra characteristic, i.e... damping value, direction of the spectrum, type of the spectrum and the associated transient excitation responses.
Description
- A response spectrum is a graph that shows the maximum response, whether displacement, velocity, or acceleration of multiple oscillators with different natural frequencies, all subjected to the same base excitation such as a vibration or shock.
- The damping value is in the units of fraction of critical damping.
- Define Vector is used to define the excitation direction.
- Under Spectrum Type, the input spectrum can be specified of either displacement/velocity or acceleration type.
- Excitation table define response as a function of frequency.
