Dynamic Modeling of Large-Scale Magnetorheological Damper Systems for Civil Engineering Applications
Yang, Guangqiang, Auteur ; Billie F. Spencer, Auteur ; Hyung-Jo Jung ; Carlson, J. David ; Ghanem, Roger G., Éditeur scientifique |Magnetorheological (MR) dampers are one of the most promising new devices for structural vibration mitigation. Because of their mechanical simplicity, high dynamic range, low power requirements, large force capacity, and robustness, these device[...]

Brian M. Phillips, Auteur ; Billie F. Spencer, Auteur |Hybrid simulation combines numerical simulation and experimental testing in a loop of action and reaction to capture the dynamic behavior of a structure. With an extended time scale, convergence of the desired displacements or forces can be assu[...]

Johnson, Erik A., Auteur ; Masud, Arif, Éditeur scientifique ; Fujino, Yozo ; Billie F. Spencer ; Baker, Greg A., Auteur |Stay cables, such as are used in cable-stayed bridges, are prone to vibration due to their low inherent damping characteristics. Transversely-attached passive viscous dampers have been implemented in many bridges to dampen such vibration. Severa[...]

Nakata, Narutoshi, Auteur ; Billie F. Spencer, Auteur ; Amr S. Elnashai, Auteur |Due to the nonlinear nature of coordinate transformations, evaluation and calibration of multiaxial loading systems in global Cartesian coordinates are challenging problems. This study proposes a systematic calibration method for multiaxial load[...]

Jian Li, Auteur ; Billie F. Spencer, Auteur ; Amr S. Elnashai, Auteur |Substructure hybrid simulation of engineering structures subjected to multiple-support excitation (MSE) is investigated. In time-history analysis of MSE problems, the equations of motion are generally posed in relative coordinates (designated EO[...]
