The representation of structural dynamics in the absence of physics-based models, is often accomplished through the identification of parametric models, such as the autoregressive with exogenous inputs, e.g. ARX models. When the structure is amenable

Publikováno v: Engineering Structures. 171:1007-1016

The present study focuses on employing an efficient control strategy to vibration mitigation for a spatial tensegrity beam composing of five typical quadruplex units. The active control approach is implemented in order to maintain the structural inte

Experimental Vibration Analysis for Civil Structures

This study tackles the challenge of operational damage identification on wind turbine blades and proposes a novel framework for damage detection and localization. A vibration-based scheme is proposed, which tracks the variability of the mode shape cu
