Caratterizzazione sismica di chiller isolati con sistemi anti-vibranti

As well established, maintaining the operational integrity and safety of key infrastructure during seismic events is of paramount importance. One requirement is the seismic protection of non-structural components and machinery, such as HVAC (Heating, Ventilation, and Air Conditioning) equipment, Generators and UPS (Uninterruptible Power Supply) systems. The paper is focused on the analysing seismic qualification methodologies, relevant standard and the current normative for seismic design of non-structural elements and equipments. Experimental investigations with a triaxial seismic table on an industrial chiller are briefly presented. Finally, the results of the simplified theoretical models developed to predict the amplification factor of equipment isolated with anti-vibration supports are discussed
