Special Issue Information

Dear Colleagues,

The monitoring and management of civil infrastructure (e.g., bridges, buildings, tunnels, pipelines, railways, dams) is always an important topic around the world. Smart sensing, accompanied with artificial intelligence (AI), has recently received growing interest for addressing the aforementioned concern. Smart sensing can obtain timely condition or status information about civil infrastructures during their lifecycle, and hence ensure safe construction and efficient operation by providing early warnings of damage or deterioration prior to costly repair or even catastrophic failures.

In recent years, engineers and researchers have witnessed significant advancements in the development of smart sensing technologies, such as wireless smart sensors, mobile sensing, computer vision, and NDT technologies. Their significant potential is further released, with advanced signal processing and data science, which is powered by AI technologies. Meanwhile, these technologies have enabled several full-scale instrumentations of structures under construction or in service. Combined with the collected data stream from these smart sensing systems, researchers take advantage of AI techniques for modelling environmental loadings, detecting construction risks, uncovering the degradation law of structural performance, identifying the surface and interior deficiency of structures, and quickly issuing management instructions.

The focus of this Special Issue is on presenting the latest advances in smart sensing and AI for civil infrastructure monitoring and management. Potential topics include, but are not limited to:

  • Smart sensor development (hardware or software);
  • Digital signal processing and filter design;
  • Sensor fault diagnosis and recovery;
  • Computer vision and image processing;
  • Big data management and mining;
  • Long-term performance monitoring and assessment;
  • Condition assessment or smart upgrading of infrastructure;
  • Surface or interior damage detection of structures;
  • System identification;
  • Construction monitoring and management;
  • Vibration mitigation;
  • Performance improvement of aged infrastructure;
  • Case studies of smart civil infrastructure systems (e.g., bridges, buildings, and tunnels), etc.

Bridge strikes by over-height vehicles or ships are critical sudden events. Due to their unpredictable nature, many events go unnoticed or unreported, but they can induce structural failures or hidden damage that accelerates the bridge’s long-term degradation. Therefore, always-on monitoring is essential for deployed systems to enhance bridge safety through the reliable detection of such events and the rapid assessment of bridge conditions. Traditional bridge monitoring systems using wired sensors are too expensive for widespread implementation, mainly due to their significant installation cost. In this paper, an intelligent wireless monitoring system is developed as a cost-effective solution. It employs ultralow-power, event-triggered wireless sensor prototypes, which enables on-demand, high-fidelity sensing without missing unpredictable impact events. Furthermore, the proposed system adopts a smart artificial intelligence (AI)-based framework for rapid bridge assessment by utilizing artificial neural networks. Specifically, it can identify the impact location and estimate the peak force and impulse of impacts. The obtained impact information is used to provide early estimation of bridge conditions, allowing the bridge engineers to prioritize resource allocation for the timely inspection of the more severe impacts. The performance of the proposed monitoring system is demonstrated through a full-scale field test. The test results show that the developed system can capture the onset of bridge impacts, provide high-quality synchronized data, and offer a rapid damage assessment of bridges under impact events, achieving the error of around 2 m in impact localization, 1 kN for peak force estimation, and 0.01 kN·s for impulse estimation. Long-term deployment is planned in the future to demonstrate its reliability for real-life impact events. Full article
