摘      要：An industrial building is a non-classically damped system due to the different damping properties of the primary structure and *** objective of this paper is to quantify the range of applicability of the real model superposition approximation method to the seismic response calculation of industrial *** analysis using lumped mass-and-shear spring models indicates that for the equipment-to-structure frequency ratiosγf1.1 orγf***,extensive parametric analyses are conducted,where both steel structures and reinforced concrete structures with equipment with various damping ratios are ***,the finite element analysis of a five-story industrial building is adopted to validate the proposed range of applicability.
