Since 2007, the EUCENTRE Foundation has been carrying out tests on structural bearings and anti-seismic devices (isolators and dampers).
EUCENTRE laboratories have several test facilities including:
- A Bearing Testing System (BTS) dedicated to the experimental characterization of structural bearings (elastomeric, POT and spherical bearings) and seismic isolation devices (elastomeric isolators and curved surface sliders);
- A Damper Testing System (DTS) dedicated to the experimental characterization of shock transmission units, displacement dependent devices and velocity dependent devices (fluid viscous dampers and fluid spring dampers).
The EUCENTRE Foundation built a strong experience testing more than 3000 isolators, 1500 structural bearings and 200 dampers.
Test protocols are performed according to the main international standards (EN1337 – Structural Bearings, EN15129 – Antiseismic Devices e AASHTO) or to customized experimental research and development campaigns developed according to Customer’s needs.
The experience gained in this field has allowed the EUCENTRE Foundation to become a Notified Body (NB-2533) to the European Commission (Reg. (EU) 305/2011) for the standard EN15129 – Anti-seismic Devices.
The EUCENTRE laboratories, meeting the requirements of DPR 380/2001 article 59, are authorized to perform acceptance tests on devices, as required by the 2018 Italian Technical Standards for Construction.
