Summary: This paper presents a study on the alternative application of satellite data in the field of Structural Health Monitoring (SHM). Land Surface Temperature (LST) and Soil Water Index (SWI) data are used to analyze the temperature and moisture condition of the soil. The statistical analysis of these records, combined with on-site experimental data and a Finite Element (FE) model, aims to understand the structural behavior and monitor the evolution of dynamic parameters.

Summary: The vibroacoustic modulation (VAM) is a nonlinear ultrasonic testing method that utilizes the modulation of a high-frequency/low-amplitude probe wave with a low-frequency/high-amplitude pumping vibration, resulting in high sensitivities to damages in the structure. A synthetic generation of the VAM signal using probe measurements acquired at different stress levels is proposed, reducing the sensing requirements and decoupling VAM from the need for a constant recurrent frequency and amplitude of the natural vibration. This method opens the possibility of applying VAM to assess the structural health of complex structures.

Summary: Structural Health Monitoring (SHM) is a valuable tool for tracking the performance and health of engineering structures over time. It relies on real-time measured data to ensure structural safety and provides recommendations for maintenance and management. The concept behind SHM is that changes in mass or stiffness will affect a structure's response to vibrations.

Summary: This paper reports the structural dynamic behaviors of a skyscraper under operational conditions using a wireless distributed synchronized data acquisition system. The system is developed to conveniently acquire the structural responses from the skyscraper with the GNSS time information. The synchronization accuracy of the system is validated by comparing the modal parameters estimated by wired central data acquisition and the wireless system. The dynamic properties of the skyscraper are presented through operational modal analysis. Additionally, a continuous dynamic monitoring system is developed to capture the long-term structural responses at different spatial positions, and the structural dynamic behaviors of the skyscraper under normal wind, typhoon, and earthquake conditions are reported.

Summary: Offshore wind turbines require remote monitoring technologies for damage diagnosis and prognosis. This study focuses on developing mechanics-based digital twins through a model-updating process, allowing for accurate response prediction and identification of input loads and uncertainty quantification. The Bayesian approach leads to slightly better results in accurate response prediction compared to the classical modal-based model updating method.

Summary: A new time-domain probabilistic technique based on hierarchical Bayesian modeling framework is proposed for calibration and uncertainty quantification of hysteretic type nonlinearities of dynamical systems. The technique introduces probabilistic hyper models for material hysteretic model parameters and prediction error variance parameters, considering both the uncertainty of the model parameters and the prediction error uncertainty. The technique employs a new asymptotic approximation to simplify the process of nonlinear model updating and reduce the computational burden. Numerical examples demonstrate the accuracy and performance of the proposed method.

Summary: This paper proposes an iterative optimal sensor placement (OSP) framework for structural identification and model updating using mobile sensors. The OSP is performed iteratively to minimize information entropy in estimating the model's updating parameters. A forward sequential sensor placement algorithm is used to solve the OSP problem at each iteration. The proposed framework is applied to a numerical case study and shows better model updating results compared to using an optimal static sensor configuration with a larger number of sensors.
