Abstract

SigmaSpectra

SigmaSpectra is a computer program that selects suites of of earthquake ground motions from a library of ground motion such that the median of the suite matches a target response spectrum at all defined periods, and then scales the suite such that the standard deviation agrees with the target standard deviation. The success of the SigmaSpectra in matching the target response spectrum and standard deviation depends on many factors including: the size of the requested suite, the number of motions in the ground motion library, and the appropriateness of the target response spectrum and standard deviation to the motions in the library.
