Response Spectrum Analysis

Response-spectrum analysis is a statistical type of analysis for

the determination of the likely response of a structure to

seismic loading.

Response-spectrum analysis seeks the likely maximum response

to these equations rather than the full time history.

The earthquake ground acceleration in each direction is given

as a digitized response-spectrum curve of pseudo- spectral

acceleration response versus period of the structure.
