Bearing Test System

The BTS (Bearing Test System) is an advanced experimental device designed to test the performance of seismic isolation and dissipation devices, such as rubber isolators, structural bearings, and metal or viscous dissipators, in a laboratory setting. The system can reproduce the stresses that these elements experience during an earthquake in a controlled manner by applying horizontal and vertical loads statically, cyclically or dynamically.

Thanks to its high-performance structure and ability to generate multi-axial movements, the BTS can assess the mechanical behaviour and durability of these devices with great precision by simulating extreme real-world conditions. It is a vital tool for qualifying products intended for the seismic protection of buildings, bridges and strategic infrastructure. Data collected during testing not only ensures compliance with regulations, but also improves the design and reliability of insulation systems, supporting scientific research and technological innovation in the field of seismic safety.

The BTS is accredited to certain standards, attesting to the quality of testing carried out by the centre. These accreditations ensure that the products tested not only meet the technical requirements, but can also be used with maximum reliability in strategic or highly seismically vulnerable works. Data collected during testing also contributes to scientific research and the continuous improvement of seismic protection technologies, providing valuable support to the fields of engineering and structural safety.
