| Abstract: | This paper describes the wave propagation and vibration characteristics of mono-coupled structures which are of spatially periodic nature; particular emphasis is laid on studying finite damped periodic systems with composite structural elements. The receptance approach to periodic structure theory is applied to study thd vibrational power flow of a base-isolated multi-storey building due to horizontal ground motion. Numerical results indicate the influence of the building impedance the properties of the isolator and the fundamental vibration frequency of the system. It has been pointed out that a finite periodic column with concentrated masses model for a building can be used to provide further insight into the vibrational characteristics of a multi-storey building. |
