Special Issue Information

Dear Colleagues,

Structures and infrastructure are susceptible to different types of damage as they age or experience altering events. Moreover, it is acknowledged that even if a structure survives a catastrophic event (such as a large earthquake) and remains undamaged, it may not be able to survive future catastrophic events (such as aftershocks or a typhoon). This is why a continuous structural assessment is necessary for structures and infrastructure, both during their lifetime and in the aftermath of a catastrophic incident. Thus far, the structural assessment of cities has heavily relied on visual inspections, which suffer from three significant drawbacks, as follows: (1) subjective judgment, (2) lack of experts, and (3) lengthy process. The aim of this Special Issue is to provide a scientific basis and offer practical solutions for smart city-based structural health monitoring through the application of nondestructive testing methods. By leveraging these advanced techniques, we aim to overcome the above-mentioned drawbacks and accelerate structural assessments. While a range of research on nondestructive structural health monitoring will be considered, the focus of this Special Issue will be placed on practical solutions that can be implemented at a city-wide scale to generate damage maps or assess the structural deterioration of buildings across an entire urban landscape.

Considering the explanations provided, topics of interest include the following:

  • Advancements in structural health monitoring (SHM) methodologies;
  • Short- and long-term structural health monitoring;
  • Novel nondestructive damage detection methods;
  • Digital twins for structural health monitoring;
  • Digital twins for city-scale structural deterioration scenarios;
  • City-scale damage maps after earthquakes;
  • Smart city-based damage detection methods;
  • Signal processing-based damage detection methods;
  • Reliability, risk, and resilience assessments of structures;
  • Deep learning application for SHM purposes.

Despite extensive research on fiber-reinforced lightweight concrete, the synergistic effects of combining different types of fibers, such as polymer and basalt fibers, on the mechanical properties and durability of lightweight concrete have not been fully investigated. This study aims to fill this scientific gap by examining the combined use of polymer and basalt fibers to enhance the performance of lightweight concrete (LWC). Lightweight concrete is widely used to reduce the weight of structures and improve seismic performance. However, its brittle nature and lower mechanical properties compared to normal-weight concrete (NWC) limit its application in high-stress environments. This study seeks to overcome these limitations by optimizing the use of polymer and basalt fibers to improve the mechanical properties and durability of lightweight concrete. In this research, 320 cylindrical samples were prepared, and the results show that adding 1% polymer fibers significantly improved the compressive and tensile strengths of lightweight concrete by 24.4% and 66.13%, respectively, at 28 days. Additionally, the combination of polymer and basalt fibers showed a positive synergistic effect, leading to improved mechanical properties and durability of the concrete, including a 45.38% reduction in final water absorption and a 43.15% reduction in chloride ion penetration at 90 days. This study provides new insights into the synergistic effects of polymer and basalt fibers in lightweight concrete and proposes a practical solution for improving its mechanical properties and durability. The findings of this research contribute to the development of lightweight concrete structures with greater reliability and flexibility. Full article
