LNEC tests 2-story building with base seismic isolation system LNEC tests 2-story building with base seismic isolation system

A highly relevant test will take place at the LNEC seismic table, in terms of audience – more than 100 people will pass through the test room over three days of tests – and dimensions of the building under evaluation at the Laboratory facilities – a real structure of two floors, six meters high and 40 tons.

The test, requested by EPS - Earthquake Protection Systems, will be monitored in person by design engineers, researchers and policy makers, and will allow the applicability of an advanced seismic isolation technology to protect structures to be assessed. EPS, which has already carried out dozens of tests of its devices on a seismic table, is carrying out only its second test in Europe, having chosen LNEC to test its "Tripple PendulumTM isolator" device.

From today until Friday, several historical earthquakes of various magnitudes will be simulated to observe the behavior of a system that aims to ensure the post-earthquake functionality of infrastructure. To demonstrate the effectiveness of the system in mitigating damage to non-structural elements, the upper floor of the building to be tested on the seismic table is furnished and has elements representative of the supply infrastructure of a real building.

The trial at LNEC can be followed HERE.

The main objectives of the test are:
• Raising awareness of the importance of post-earthquake functionality, particularly in critical infrastructure;
• Bringing academia, state laboratories and the technical community closer together in the development and implementation of innovative solutions to ensure the safety and resilience of buildings;
• Demonstration of the effectiveness of the triple pendulum system for base insulation in buildings.
