Abstract

An accurate and efficient method for seismic analysis of multiply supported, multi-degree-of-freedom secondary subsystems is developed. The method accurately accounts for the effects of tuning, interaction, non-classical damping, and spatial coupling which are inherent characteristics of composite primary-secondary systems. The method consists of two steps: (a) synthesis of the modal properties of the composite primary-secondary system in terms of the known modal properties of the two subsystems, and (b) determination of the secondary subsystem response in terms of the derived modal properties and the ground response spectrum. The method is efficient since it avoids large eigenvalue solutions and time-history calculations.
