International Distributed Hybrid Simulation of 2-Span Continuous Bridge

Abstract eng:
To evaluate a seismic response of bridge systems, it is important to adopt the most appropriate model for each component. In this study, the seismic response of a bridge with a C-bent and a single RC pier and a steel pier is evaluated. Whereas the single RC pier is modeled by the fiber model, the C-bent RC and the steel pier are modeled by the hybrid experimental models because any numerical models cannot take into account their strong nonlinear behavior. OpenSees and OpenFresco are used to conduct the international hybrid simulation. As the results of the international hybrid simulation between Kyoto Univ. and UC Berkeley, the nonlinear seismic response of the bridge system can be obtained and the distributed hybrid simulation is found to be a powerful tool for the evaluation of structural systems.
