Tian-Wei Ma, Auteur ; Yang, Henry T., Auteur ; Ghanem, Roger G., Éditeur scientifique |This paper proposes a combined feedback-feedforward control algorithm for reducing structural response of buildings to seismic excitations. The controller contains both feedback and feedforward components. The feedback component is assumed to be[...]

Pala, Yasar, Auteur ; Guney, Ibrahim, Auteur ; Karadere, Gultekin ; Ghanem, Roger G., Éditeur scientifique |In this study, the analytical solution of the direct dynamics problem that mostly requires some numerical techniques is developed for two important cases. In the first case, two coupled differential equations of the motion of a particle acted up[...]

Bayesian Analysis of the Phase II IASC-ASCE Structural Health Monitoring Experimental Benchmark Data
Ching, J., Auteur ; James L. Beck, Auteur ; Ghanem, Roger G., Éditeur scientifique |A two-step probabilistic structural health monitoring approach is used to analyze the Phase II experimental benchmark studies sponsored by the IASC–ASCE Task Group on Structural Health Monitoring. This study involves damage detection and assessm[...]

Nicos Makris, Auteur ; Cameron J. Black, Auteur ; Ghanem, Roger G., Éditeur scientifique |In this paper the response of a bilinear oscillator subjected to pulse-type motions is revisited with dimensional analysis. Using Buckingham’s Πtheorem the number of variables in the response analysis is reduced from six (6) to four (4). When th[...]

Nicos Makris, Auteur ; Ghanem, Roger G., Éditeur scientifique ; Cameron J. Black, Auteur |In this paper, the inelastic response of rigid-plastic and elastic-plastic systems subjected to pulse-type excitations is revisited with dimensional analysis. Starting from Newmark’s result on the maximum displacement of a sliding mass resting o[...]

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[...]

Nicos Makris, Auteur ; Cameron J. Black, Auteur ; Ghanem, Roger G., Éditeur scientifique |This paper investigates the ’goodness’ of peak ground velocity as a dependable intensity measure for the earthquake shaking of civil structures. The paper stresses the importance of distinguishing between acceleration pulses and velocity pulses,[...]

Pol D. Spanos, Auteur ; Ghanem, Roger G., Éditeur scientifique ; Failla, Giuseppe, Auteur |A wavelets-based method is developed to estimate the evolutionary power spectral density (EPSD) of nonstationary stochastic processes. The method relies on the property that the continuous wavelet transform of a nonstationary process can be trea[...]
