New Nautilus Evo improves seismic resistance at Gruppo Grassi office

• • Seismic-prone areas increase the risks of structural damage to buildings caused by earthquakes.

  • Studio Giuseppe Passaro Architects & Engineering Costruzioni implemented a structural resistance solution in Gruppo Grassi office building.

  • New Nautilus Evo reduced concrete use, improving seismic resistance and overall structural performance.

Seismic-prone areas raise the structural stakes

In seismic-prone areas such as Montemurlo, Italy, buildings are exposed to increased risk of structural damage during earthquakes. 

These events can lead to cracking and deformation of structural elements, and, in severe cases, partial or total failure. Ensuring the safest building response to dynamic forces is essential to prevent long-term damage.

A resistance-focused solution for a complex project

For the Gruppo Grassi office building, Studio Giuseppe Passaro Architects & Engineering Costruzioni selected New Nautilus Evo, a solution focused on structural performance and practical, on-site execution. 

The main challenges were: 

• seismic-prone site,
• the building’s irregular geometry,
• support points at different heights due to the terrain configuration.

Within this context, New Nautilus Evo contributed to a more efficient structural performance while adapting to the project’s complexity.

Reduced concrete use for improved structural performance

New Nautilus Evo was used to reduce concrete volume by creating voids where material is not structurally necessary.  Lowering mass volumes is an effective strategy for improving seismic resistance by reducing inertial forces and stress on key structural elements. In this way, the solution contributed to improved overall structural performance under seismic conditions of this area.
