What are the response spectra in seismic analysis?
In seismic analysis, the response spectra are a graphical representation of the response of a structure (plotted in Y-Axis) vs the natural frequency of the structure (plotted in X-Axis) to the input ground motion. The response can be anything displacement, velocity or acceleration. The series of maximum responses of all possible single-degree-of-freedom systems of given damping towards the given ground motion were plotted to get response spectra. It is called spectra because the responses of various single-degree freedom systems having different natural frequencies are plotted in a single graph.
