While real-time hybrid simulation has been utilized for structures subjected to seismic events for decades, its use in fluid-structure interaction problems is still a novel endeavor. Gathering data for cascading seismic and tsunami events is difficult due to space constraints in existing experimental facilities, complications regarding the application of scaling laws for both the fluid and structure, and limitations of software in simulating multiple hazards within the same analysis.
We just completed our first round of experiments using a real-time hybrid simulation (RTHS) testing method to study fluid structure interaction. A cylindrical bridge pier specimen and three-dimensional numerical bridge model were subjected to cascading seismic and tsunami events within a three-tier real-time hybrid simulation architecture. Textbook impulse response was exhibited by the specimen, and we confirmed that a hydro-RTHS appraoch is both feasible and economical for future investigations on this topic.
