Damage Identification Study of a Seven- Story Full-scale Building Slice Tested on the Ucsd-nees Shake Table
A full-scale seven-story reinforced concrete building section was tested on the UCSDNEES shake table during the period October 2005 January 2006. The shake table tests were designed to damage the building progressively through four historical earthquake records. At various levels of damage, ambient vibration tests and low amplitude white noise base excitations with root-mean-square acceleration...
متن کاملUncertainty Analysis of System Identification Results Obtained for a Seven Story Building Slice Tested on the UCSD-NEES Shake Table
A full-scale seven-story reinforced concrete building section/slice was tested on the NEES shake table at the University of California San Diego during the period of October 2005 to January 2006. Three output-only system identification methods were used to extract the modal parameters (natural frequencies, damping ratios, and mode shapes) of the test structure at different damage states. In thi...
متن کاملExperimental characterization, modeling and identification of the NEES-UCSD shake table mechanical system
This paper proposes a simple conceptual mathematical model for the mechanical components of the NEESUCSD large high-performance outdoor shaking table and focuses on the identification of the parameters of the model by using an extensive set of experimental data. An identification approach based on the measured hysteresis response is used to determine the fundamental model parameters including t...
متن کاملIdentification of the Mechanical Subsystem of the NEES-UCSD Shake Table by a Least-Squares Approach
A least-squares method is used to determine the fundamental parameters of a simple mathematical model for the mechanical subsystem of the NEES-UCSD large high performance outdoor shaking table. The parameters identified include the effective horizontal mass, the effective horizontal stiffness, and the coefficient of the classical Coulomb friction and viscous damping elements representing the va...
