Earthquakes and Structures – How to Mitigate Seismic Effects Exhibition

“Earthquakes and Structures – How to Mitigate Seismic Effects” is a traveling exhibition created by the EUCENTRE Foundation with the support of the Italian Civil Protection Department. Its goal is to raise awareness about the seismic vulnerabilities present across Italy and the possible mitigation measures that can be implemented.
The exhibition includes a section dedicated to the concept of seismic risk, followed by an introduction to both structural and non-structural prevention strategies in the context of civil protection. The next part of the exhibition focuses on civil protection structural activities, with particular attention to the knowledge of past earthquakes in Italy, the structural vulnerabilities of the most common building types, the intervention techniques to reduce these vulnerabilities and the technological and scientific advancements in seismic risk mitigation.

In addition to the informative displays, the exhibition features a hands-on experience where participants can explore the phenomenon of resonance and observe the difference in behavior between a seismically isolated and a non-isolated structure, through simulations using the Compact Simulator System.
The visit concludes with the “earthquake experience”, in which participants can feel the tremors of the same earthquake under different conditions: at ground level, on the fifth floor of a reinforced concrete building, and inside a seismically isolated structure. This immersive experience, guided by expert staff, helps participants understand what it feels like to experience an earthquake and how the structural response influences the perception of the shaking.

Compact Seismic Simulator – CSS

The EUCENTRE Foundation takes part in public outreach events aimed at raising awareness of seismic risk, also using the Compact Seismic Simulator (CSS).
The Compact Seismic Simulator is an integrated system for simulating seismic events on scale models of structures or buildings. It is designed to operate as a true single-degree-of-freedom shake table in reduced scale. Therefore, it is capable of simulating earthquakes and generating oscillations to study both the seismic response and the natural frequencies of the tested structures.

Thanks to this device, during outreach events, it is possible to reproduce the behavior of both non-isolated and seismically isolated structures. Additionally, due to the ability to adjust the amplitude and frequency of the CSS, the resonance phenomenon can also be demonstrated.
The CSS, thanks to its high torque, can operate on specimens up to 50 kg in mass, applying accelerations up to 1.5 g and displacements up to 200 mm. It is extremely compact in size (50×90 cm) and lightweight (50 kg unloaded), making it easily transportable. Its electric motor does not require an industrial power supply and can be operated using standard household electrical systems.The actuator’s movement is controlled through a two-stage regulation system: a positioning drive and an embedded computer. The embedded computer can generate various displacement signals to be applied to the specimen: from simple linear movements and sinusoidal oscillations to the reproduction of real earthquake accelerograms.
