Structural Study of Composite Parts

Following the move of the HES-SO Valais to new buildings, the Centre Pédagogique Prévention Séisme (CPPS), which operates a vibrating table of 5x6m allowing to simulate seismic loads, wished to review the system’s safety. Previously surrounded by a security barrier, the HESSO took advantage of the opportunity provided by the new buildings to operate the table at the new pit level. The barriers can be removed in favor of extensions to close the space between the table and the edges of the pit. In this way, the table looks even more like the floor of a classroom, and this with the aim of increasing the simulated sensations. MB-Composites (https://www.mb-composite. com/), expert in the realisation of systems in composite materials was mandated by the HES-SO to build this table extension. The Countdown Company was in charge of the concept validation.
