Special Issue Information

Dear Colleagues,

The development and prosperity of modern societies are interrelated with crucial functions that are facilitated by numerous structures and infrastructures. The latter, being related to varying size, geometry, material and complexity, are frequently exposed to both hazardous actions (earthquakes, tsunamis) and aging effects (corrosion, fatigue) that can deteriorate the performance of the civil engineering structures. Thus, the ability to monitor the response of the structures during their lifetime is of high importance in order to secure the structural integrity, the reliability as well as the functionality of those systems.

Structural Health Monitoring (SHM) is defined as an integrated process that enables to monitor the performance and assess the condition of structures by exploiting on-structure sensing technology and numerical tools. Significant research and industrial effort has been already spent to develop and advance SHM systems that aim to reliably monitor structural health, identify structural deficiencies and damages as well as favor the integrity management. However, SHM and the pertinent technology are still associated with tremendous challenges. This is mainly due to the inherent complexity of the structural systems and their behavior to various exposures, the defects of the sensing systems as well as the limitations of existing numerical methods required to transform the monitored response to structural health information.

This Special Issue is dedicated to highlight the current state-of-the-art advances and the latest applications of the SHM technology. We welcome high quality articles addressing, among others, the following topics:

  • state-of-the-art review of SHM techniques for civil engineering structures;
  • advances on the sensing technology to be used for SHM;
  • advances on vibration-based SHM;
  • novel methods to assess the structural condition and detect structural damages;
  • recent developments and advances for integrated SHM and decision-support to facilitate structural integrity management purposes;
  • case studies of advanced SHM employment for civil engineering structures.

The Five-hundred-meter Aperture Spherical radio Telescope (FAST) is one of China’s major pieces of national infrastructure. A variable cable-net structure is used as the main supporting structure of the active reflector. The displacement of the cable net works through actuators. The realization of linkage control is a multi-degree-of-freedom and complex coupling control system. Due to factors such as the temperature difference between day and night, as well as actuator failure, the reflector control accuracy and even structural safety are affected during the position-control process of the cable net, so realizing evaluation of control accuracy and fault warning of the reflector is a significant problem. This paper proposes a pre-evaluation and health monitoring system based on advanced mechanical simulation technology. Through this system, on-site staff can expeditiously analyze the model to determine whether the cable net is currently in a safe state, predict the fatigue degree of the components, and maintain the structure when appropriate. The pre-evaluation and health monitoring system adequately ensure the stable functioning of the FAST cable net, improve the efficiency of on-site maintenance work, and markedly reduce the safety risk of the structure.
