Abstract: Most of the previous studies considered structural system identification in the continuous‐time domain. The discrete‐time approach to the problem is more natural since all the recordings are in the discrete‐time form. This ...

Abstract: A discrete-time analysis of seismic site amplification in layered media for vertically propagating shear waves is presented. The discrete-time approach not only is simpler and more accurate than the previously suggested ...

Abstract: Recently developed adaptive methods for modeling, identification, and control are now being successfully used in various branches of science and engineering. These methods present significant advantages over the classical ...

Abstract: A concise review of the fheory of adaptive modeling, identification, and control of dynamic structural systems based on discrete‐time recordings is presented. Adaptive methods have four major advantages over the classical ...

Abstract: This paper presents a discrete-time wave-propagation method to calculate the seismic response of multistory buildings, founded on layered soil media and subjected to vertically propagating shear waves. Buildings are modeled ...

Abstract: Soil-structure interaction (SSI) can significantly alter the characteristics of recorded motions in buildings. The dominant frequency recorded in a building subjected to SSI is always smaller than the dominant frequencies ...

Abstract: A method to estimate the center of rigidity of buildings by using vibration recordings is presented. The method is based on the criterion that the coherence of translational motions with the rotational motion is minimum ...

Abstract: Structural response to one‐ and three‐dimensional (3D) simulated motions in San Bernardino Valley, Calif., from a hypothetical earthquake along the San Andreas Fault with moment magnitude 6.5 and rupture length of 30 km ...

Abstract: This study examines the rationale of Hilbert-Huang transform (HHT) for analyzing dynamic and earthquake motion recordings in studies of seismology and engineering. In particular, this paper first provides the fundamentals ...
