Procedures for Developing Multi-Period Response Spectra at Non-Conterminous United States Sites
Procedures for Developing Multi-Period Response Spectra at Non-Conterminous United States Sites
FEMA P-2078 | August 2020
This study develops methods for constructing multi-period response spectra (MPRS) at all periods and site classes of interest, assuming that only deterministic and probabilistic values of SS and S1, and approximated values of TL from ASCE 7-16, are available for the site of interest. A comparison between derived MPRS and calculated MPRS at sites in the conterminous United States was used to validate the proposed methods and models. With this validation, these method and models can be used to derive multi-period response spectra using only the three currently available ground motion parameters SS, S1, and TL for all non-conterminous United States regions of interest.
