Special Issue Information

Dear Colleagues,

Vibrations induced by exogenous dynamic forces are crucial to any civil structure, e.g., buildings, bridges, tunnels, etc. It is a challenging task to keep these aforementioned structures in a safe condition during an extreme natural or man-made disaster. Therefore, modern structures are using vibration-based structural health monitoring (SHM) to keep track of the changes in these structures. Sensors (e.g., accelerometers, velocimeters, displacometers, geodetic sensors) play a vital role in SHM; simply, without sensory information, SHM is unimaginable. To ensure safety, important structures, e.g., bridges, are accompanied by various control devices, such as passive, active, hybrid, intelligent, and semi-active. As a result, SHM requires more attention due to the underlying complexity of monitoring strategies (e.g., control algorithms) and technologies (e.g., smart devices). Furthermore, non-physics-based modeling based on measured sensory information is also gaining attention as part of SHM that may help identify underlying systems as well as assist in detecting damage. It is possible to implement both real-time and offline monitoring to reduce any unexpected damage and also provide an early warning to avoid any serious events, e.g., collapse.

The aim of this Special Issue is to collect state-of-the-art scientific knowledge from experts. Contributions may include the following topics: scientific research papers, novel methodology in SHM, implementations and case studies, state-of-the-art reviews, assessments and quantifying damage, system identification, etc.

To address the shortcomings of tuned mass dampers (TMD), such as excessive internal space occupation and overlarge physical mass, this paper proposes a tuned façade damper inerter (TFDI) that utilizes parts of the outer façades of double-skin façades (DSF) as damping mass, capitalizing on the lightweight and efficient characteristics of inerters. The TFDI effectively resolves the challenge of multi-layer connections of inerters in high-rise buildings by utilizing corridor space. By vertically distributing TFDIs, a distributed multiple TFDI (d-MTFDI) system is formed. The configuration and motion of equations of this system are presented, and the control effectiveness is validated using wind tunnel test data. Two tuning modes are further proposed: unified tuning mode and distributed tuning mode. For the unified tuning mode, analytical expressions for optimal tuning frequency and damping ratio are derived; for the distributed tuning mode, numerical optimization methods are employed to determine the optimal tuning frequency range and damping ratio. Comparative results indicate that the distributed tuning mode achieves higher control efficiency than the unified tuning mode, with a significant reduction in the required optimal damping ratio. Furthermore, comparisons with d-MTMD demonstrate that d-MTFDI significantly enhances wind-induced vibration control performance. Full article
