Generate floor response spectra: Part 1. Direct spectra-to-spectran method

摘要

A direct spectra-to-spectra method is developed for generating floor response spectra (FRS), which are used as input for seismic design and assessment of secondary systems in nuclear facilities. Only ground response spectra (GRS) and basic modal information of primary structures, including natural frequencies, modal damping, participation factors, and mode shapes, which can be readily obtained from a modal analysis, are needed. In tuning cases, when equipment is resonant with the primary structu
