Direct Spectra-to-Spectra Methods

Updated 2024-08-22 Published 2024-07-08

The two investigated DSSMs in this study can be concluded to perform well in comparison to the more well-established time series method for evaluation of FRS, and are judged adequate to use in various design situations.

The obtained floor response spectra (FRS) using the two studied direct spectra-tospectra methods (DSSM) and the time series method show an overall good agreement in shape and acceleration response at the peaks. The results also show that there is a significant scatter at the peaks between the individual FRS obtained from the time history analyses. These results highlight the importance of using several sets of acceleration time series followed by averaging of the results when using this method. However, the FRS obtained using either of the two DSSMs mainly fall within the scatter of the time-history based FRS.
