What is a direct spectra-to-spectra method?
I am working on an equipment platform on a Risk Category V structure, and am working on developing an in-structure response spectra, however the UFC states "In the application of ASCE 4-98 Section 3.4, those provisions that relate to spectra-to-spectra analysis in Section 3.4.2.1.2 shall not apply."
Section 3.4.2.1.2 basically states direct spectra-to-spectra generation techniques may be used, but I am not familiar with those techniques (or at least not that I am aware of) to know if I am using them or not. My assumption is that they are techniques to develop something equivalent to an in-structure response without having to analyze the structure; a way to approximate an in-structure response. Is that correct? Are there any publications that delineate the procedures of structure-to-structure response? I have not been able to find any.
