Special Issue Information

Dear Colleagues,

Civil structural health monitoring has become significantly more important within recent decades due to the rapidly growing demand for new constructions worldwide with respect to limited space and increased sustainability, as well as longer service lifetimes of existing structures. Knowledge about the structural performance is essential to the planning and design of condition-based maintenance works. Fiber optic sensing can be beneficial to obtain internal structural characteristics such as strain, temperature, or vibration over long distances. Discrete fiber Bragg gratings or even fully distributed sensing cables are directly embedded inside or attached along the infrastructure, which enables overall assessment of the structural behavior and performance.

The Special Issue invites researchers and experienced engineers to submit their original articles and reviews discussing recent research developments or real-scale monitoring approaches based on fiber optic sensing in civil engineering applications.

An often-utilized solution in terms of providing support to underground excavation, the fully grouted rebar rock bolt system presents optimization potential due to existing technological limitations in capturing and understanding its composite system response. In order to address these limitations, the development and application of Distributed Optic Fiber Sensing (DOS) allows for continuous strain monitoring (at a spatial resolution of 0.65 mm utilizing the technique defined herein) across a full spectrum of loading. A robust laboratory investigation was conducted featuring 24 rock bolt specimens. This examined the effects of two selected independent variables: rib spacing (from 13 mm to 68 mm) and grout annulus (from 7.7 mm to 22.8 mm). This body of research provides valuable insight into the performance of grouted rebar rock bolts and the effects of the selected parameters (rib spacing and size of the grout annulus), while also highlighting an advanced monitoring technique. Results indicated that rib spacing was a negative predictor of bond performance. No definite conclusions were drawn in terms of the effect of the size of grout annulus; however, findings provide limited support for an optimal sizing in relation to rib height. The results were also compared to analytic and numerical models. These insights can aid in calibrating and validating numerical models, and improve monitoring and rock bolt design within the overall goal of improving and optimizing ground support design arrangements.
