Spectral Response Maps
Following earthquakes larger than magnitude 5.5, spectral response maps are made. Response
spectra portray the response of a damped, single-degree-of-freedom oscillator to the recorded
ground motions. This data representation is useful for engineers determining how a structure
will react to ground motions. The response is calculated for a range of periods. Within that
range, the International Building Code (IBC) refers to particular reference periods that help
define the shape of the "design spectra" that reflects the building code.
