The ELISSA European Union research project, which involved our technical partners Cocoon and Knauf, studied how a pre-fabricated construction in lightweight steel behaves during an earthquake.

The structure holds up during an earthquake with acceleration of 1g (that is, 150% stronger than the quake in L’Aquila in 2009, which had a magnitude of 6 on the Richter scale). During the ELISSA (Energy Efficient Lightweight-Sustainable-Safe-Steel Construction) project, partners coming from the worlds of research and industry spent more than three years developing lightweight, high-performing steel constructions.

The project focused on the construction of walls and ceilings to create a two-storey “ELISSA house” prototype with a lightweight steel construction system and with a surface limited to 11 square metres.

The University of Naples, which specialises in this industry, carried out various tests on the prototype to evaluate a few of its dynamic properties. The reference used was the earthquake in L’Aquila on 6 April 2009, with an intensity of 9 on the Mercalli scale and a magnitude of 6 on the Richter scale.

In all the tests, the ELISSA house scored extremely well in terms of anti-seismic performance: subjected to oscillations 1.5 times greater (scale factor of 150%) than those of the earthquake in L’Aquila, it didn’t show any visible signs of damage on its constructive components.
