This paper describes the seismic design analysis methods, considering the correlation coefficients of seismic responses with multi-directional excitations. Through the numerical study, we focused on the seismic responses of simple secondary structures fixed on some floor level of the building structure which has the base excitation of El-Centro earthquake. Seismic response of secondary structure is introduced by the response spectrum analysis applying CCFS(Cross-oscillator, Cross-Floor response Spectrum) method to the multi-directional excitation problem. As the results, it is found the effective extension for the seismic design of multi-directional excitations to apply the CCFS analysis approach.
