Modal Dynamic Analysis
NISA II/DYNAMICS is an independent module and can be used
in conjunction with NISA II to solve a wide variety of problems
encountered in dynamic analyses using Modal Superposition.
The following analysis features are available:
- Transient Dynamic Analysis to evaluate the response of a
given structure to an arbitrary loading.
- Shock Spectrum Analysis may be used to determine the
response of a structure to an arbitrary oriented shock input
- Frequency Response Analysis can be used to compute the
steady state response of a structure to harmonic loads
defined by amplitude and phase spectra.
- Random Vibration Analysis can be used to obtain the
statistical parameters of response quantities such as power
spectral densities (PSD) and mean square values of structures
subjected to a stationary random loading or ground
excitation (such as earth uake, etc.).
