This presentation outlines the ongoing development and implementation of
real-time hybrid simulation (RTHS) for wave-structure interaction
applications, termed hydro-RTHS, at the NHERI-EF Large Wave Flume and
Multi-directional Wave Basin at Oregon State University (OSU). This
hydro-RTHS framework couples physical wave loading with computational
structural models. Parameters difficult to model physically in wave
experiments are modeled numerically, virtually extending OSU’s experimental
capabilities. This approach is practical as it physically simulates the
wave-structure response.



*HS 201: ADVANCES IN MULTI-AXIAL REAL-TIME HYBRID SIMULATION*

*MECHS WEBINAR*

Real-time hybrid simulation (RTHS) is an efficient and cost-effective
experimental testing technique for performance evaluation of structural
systems subjected to dynamic loading (e.g., wind and earthquakes) and with
rate-dependent components. When structural components are subjected to
multi-axial loading, multiple actuators are essential to impose realistic
boundary conditions over the physical specimens in the laboratory. However,
this loading assembly will exhibit significant dynamic actuator coupling
and suffer from synchronization errors and potential instabilities during
the test execution.
