Abstract: This paper deals with the response spectrum analysis method of the secondary structures including the correlation effects between nonuniform support excitations. Based on the random vibration theory, the multiple floor response spectra and their cross-correlation coefficients are derived from the design ground response spectrum. The example analysis results show that the proposed method yields more accurate results than those by the conventional multiple floor response spectra method without considering the correlation effects. The present method may be easily employed in the seismic design of the secondary structures in engineering practice.
