Depending on the availability of input data related to an earthquake event, methods for seismic response analysis of structures may be classified under: (i) time history analysis; (ii) response spectrum method of analysis; and (iii) frequency domain spectral analysis.

While the time history analysis is applicable for both elastic and inelastic ranges of response, the other two methods are essentially valid within the elastic range.

IntelliSIMS has a skillful team analysis to perform all types of seismic response.
