- 【标题】Range of applicability of real mode superposition approximation method for seismic response calculation of non-classically damped industrial buildings
- 【摘要】An industrial building is a non-classically damped system due to the different damping properties
of the primary structure and equipment. The 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 buildings.
The analysis using lumped mass-and-shear spring models indicates that for the equipment-to-structure frequency
