A Program for  Response Spectra of Nonlinear and Linear Systems







Developed at the University at Buffalo, nSPECTRA is a computer program for obtaining the response spectra of nonlinear or linear systems. 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 perform the time response analysis for a particular simple nonlinear structure (sdof).

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. If you are not familiar with the program's capabilities feel free to download it.
