TL;DR: In this article, a tuned mass-damper-inerter (TMDI) was proposed to suppress the oscillatory motion of stochastically support excited mechanical cascaded (chain-like) systems.

TL;DR: In this article, the authors considered an optimum tuned mass damper-inerter (TMDI) design framework accommodating the above effects while accounting for parametric uncertainty to the host structure properties, modeled as a linear multi degree of freedom system, and modeled as stationary colored noise.

TL;DR: In this article, a parametric numerical study is performed involving a top-floor-TMD-equipped planar frame capturing accurately the in-plane dynamic behavior of a 74-storey benchmark building exposed to a quasi-stationary spatially-correlated wind-force field accounting for vortex shedding effects in the across-wind direction.

TL;DR: In this article, the adaptive chirplet decomposition combined with the Wigner-Ville transform and the empirical mode decomposition are employed to process various non-stationary signals (strong ground motions and structural responses).

TL;DR: In this article, an integrated approach for synthesizing artificial seismic accelerograms compatible with a given displacement design/target spectrum is presented in conjunction with aseismic design applications, where a stochastic dynamics solution is used to obtain a family of simulated non-stationary earthquake records whose response spectrum is on the average in good agreement with the target spectrum.
