Summary: This study investigated the curing effect of the adhesive layer on the electromechanical admittance (EMA)-based detection of concrete structural damage. The results showed that the singular shift in EMA spectra during adhesive curing can be turned into three typical shifts when structural damage occurs, validating the analytical results.

Summary: This paper proposes a nondestructive testing method using piezoelectric sensors and electromechanical impedance technique to monitor the stress-strain relationship of concrete. The experiment verifies the relationship between the concrete conductance measured by PZT and PEC sensors and the load at the applicable frequency. The results indicate that both sensors can be used to monitor the stress and strain, while the PEC sensor has a wider applicable frequency range, lower conductance spectrum fluctuation, and shorter analysis time.

Summary: This paper conducted numerical and experimental studies to investigate the effect of heating time on the monitoring of concrete structures using surface-bonded piezoelectric (PZT) sensors. The research demonstrated that the heating time had dual dependencies on the EMA signatures, which had an amplified influence on the structural damage detection results. The findings emphasized the importance of considering the time factor when evaluating temperature influence on PZT-based concrete structural monitoring.

Summary: Structural health monitoring (SHM) is an effective strategy for monitoring important civil, mechanical, and aerospace engineering systems. The electro-mechanical impedance (EMI) technique, based on SHM, is used to study the strength properties and damages in structures. Introducing bacteria into concrete can enhance its performance and mitigate damage through microbial-induced calcite precipitation.

Summary: In the field of structural health monitoring (SHM), real-time image-based damage detection is highly demanded. Compressive sampling (CS), a promising solution to reduce power consumption, has faced limitations such as low compression ratios and the need for laborious training. To overcome these barriers, a multitask CS algorithm that relies on existing generators trained by low-pixel crack images is proposed. By exploiting the similarity in sparsity pattern among crack images, the algorithm achieves higher crack detection accuracy and efficiency. Verification using synthetic and real image data shows its potential for operational CS-based crack detection systems in real-time SHM.

Summary: This paper presents a novel approach for crack detection and localization in high-pressure fluid pipelines using acoustic emission signals, which involves scanning peaks, filtering noise, localizing emission sources through time difference of arrival technique, and eliminating false emission sources by considering wave energy attenuation characteristics. By observing the distribution of emission sources according to position and time, the method can indicate the location of irregular structural changes based on emission source distribution and density along the pipeline.

Summary: Structural health monitoring aims to detect, locate, quantify, and predict any damage occurring during the lifetime of a structure for effective maintenance and repair. The location of structural damage can be deterministic or probabilistic, requiring the monitoring system to handle both types of events. Through optimization and integration of different sensor placement methods, a global monitoring strategy has been achieved to balance the detection of predetermined and random damage locations.
