Apply high-force longitudinal motions and vertical compression to full-scale seismic isolation bearings to study their performance under real-world earthquake conditions. Deployed worldwide, these high capacity systems comprise a self-reacting frame anchored in a fixed foundation of reinforced concrete and feature a massive test platen driven by multiple servohydraulic linear actuators.
Deployed and supported worldwide: Eucentre Foundation – The University of Pavia, National Center for Research on Earthquake Engineering (NCREE)
PhD-level MTS System Integration Engineers provide expert guidance and training
State-of-the-art Control Methods: Degree-of-Freedom Control, Real-time Control, Three-variable Control, Adaptive Control
Fully turnkey solution, comprising state-of-the-art controls, full-featured application software, advanced hydro-mechanicals and fatigue-rated MTS test actuators, swivels and mounting hardware
