The program can perform the analysis for a collection of ground motions (maximum 200 ground motions) returning the response spectra for each ground motion and the average and standard deviation response spectra of the collection. The program can also print out the time history response for a particular pendulum in the spectrum.</p> <p>The purpose of this web site is to keep you up to date on the latest enhancements, as well as to help you resolve any problems you may encounter while using NSPECTRA.
