Abstract: In seismic design and analysis of secondary systems housed in structures, the most widely used approximate method is the floor response spectra approach. In this paper, necessary modifications of floor response spectra due to uncertainties in the seismic input, soil, and structural properties are addressed by introducing a rational approach based upon spectral moments of the primary-secondary structural system. Two approximate methods of secondary system analysis which take into account primary-secondary system interactions are also assessed.
