Multi-Dimensional Mixed-Mode Hybrid Simulation, Control and Applications

The fourth and final task is to validate the hybrid simulation framework through the study of the three-dimensional behavior of a skew RC bridge. First, extensive analyses of skew bridges are conducted to prepare for the hybrid simulation. Subsequently, a small-scale RC pier is experimentally tested as a physical substructure, while the rest of the piers and the bridge deck are analyzed using a finite element model. The mixed-mode control capability is employed to impose on the RC pier simultaneous gravity loads in the axial direction and earthquake-induced displacements in the other directions. The experimental results show that the multi-dimensional hybrid simulation with versatile six degrees-of-freedom loading capability is a promising approach that provides a reliable means for evaluation of the seismic performance of large and complex structural systems.
