THE DYNAMIC ANALYSE OF A CONSTRUCTION WITH THE BASE INSULATION CONSISTING IN ANTI-SEISMIC DEVICES MODELLED AS A HOOKE-VOIGT-KELVIN LINEAR RHEOLOGICAL SYSTEM
The paper presents the main results of theoretical and experimental researches regarding dynamic behaviour of constructions (building, bridge, or viaduct) with the base insulation, composed of series / parallel connection of elastomeric and dissipative anti-seismic devices. The purpose of the paper is to highlight the dynamic behaviour and the isolation capacity when the base insulation system can be constructed to respect the laws of the Hooke-Voigt-Kelvin linear rheological model. There were used the data of some rigid behaviour buildings, as well as the fundamental excitation of the 4thMarch 1977 earthquake. The carried out studies highlighted the possibility to assess the dynamic response and the isolation capacity at the action of fundamental spectral component of the 4thMarch 1977 earthquake.
Key words: isolation capacity, elastomeric and dissipative anti-seismic devices, laws of the Hooke-Voigt-Kelvin linear rheological model
