Real-time hybrid simulation (RTHS), which integrates physical experiment and numerical simulation, plays an essential role in understanding the time-dependent behavior of structures when subject to hazardous loadings. On the other hand, RTHS might not yield accurate results for complex structural systems due to experimental and computational limitations. Distributed real-time hybrid simulation (dRTHS), which takes the advantage of distributed laboratory facilities using network communications, was proposed and proven to address some limitations in RTHS. During dRTHS, Internet delay due to the network communication is added to the actuator delay in RTHS, which may cause inaccurate results or even unstable tests. To …

Masters Theses
Hybrid simulations have shown great potential for economic and reliable assessment of structural seismic performance through a combination of physically tested components, called the experimental substructure, and numerically simulated components, called the numerical substructure. Current hybrid simulation practices often use a fixed numerical model without considering the possible availability of a more accurate model obtained during hybrid simulation through an online model updating technique. To address this limitation and improve the reliability of numerical models in hybrid simulations, this study describes the implementation of an online model updating method in real-time hybrid simulation (RTHS). The Unscented Kalman Filter (UKF) was …
