Special Issue Information

Dear Colleagues,

Over the past two decades, fiber-reinforced polymer (FRP) composite materials have garnered widespread attention for the repair of existing and deteriorated infrastructure. FRP composites can enhance the durability of structures while being lightweight, facilitating the ease of installation. Extensive research has revealed that using fiberglass for shear and flexural infrastructure strengthening presents a continuous solution. The effective utilization of FRP composites in engineering infrastructure has significantly addressed major issues related to the repair and aging of existing infrastructure. This Special Issue aims to solicit research findings on the strengthening, rehabilitation, and application of FRP in civil engineering. Experiments, modeling, and case studies will all be taken into consideration. Submitted research should explicitly state its novelty and contribution to technological advancement.

This Special Issue aims to encourage scholars to explore various feasible approaches to using fiberglass in civil engineering. Topics of interest include, but are not limited to, the following areas:

  • FRP composites for concrete infrastructure;
  • FRP–steel–concrete composite structure;
  • Maintenance and operation of concrete infrastructure;
  • Sustainable development in the construction industry.

This article presents the results of an experimental campaign conducted on a set of four unreinforced masonry walls at full scale. The purpose of this study is to assess, using non-destructive methods, the impact of retrofitting and damage on the modal response of masonry wall systems. Each wall underwent a sequence of increasing cyclic displacements applied by an actuator at the upper end of the specimen. Modal tests based on vibrations were performed both before and after rehabilitation, as well as during the sequence of increasing displacements. It was demonstrated that frequencies can identify progressive damage when the maximum crack is about to occur, as well as the effect of wall retrofitting when mass contribution is considerable. However, the modal assurance criterion indicator (MAC) fails to properly identify a trend of decreasing correlations as progressive damage increases; instead, it is sensitive to detecting maximum crack and instability conditions. Furthermore, it was determined that the coordinated modal assurance criterion indicator (COMAC) does not identify the damage distribution as expected. However, the cumulative COMAC provides a useful tool for quick visualization and interpretation of COMAC behavior. Finally, a novel damage indicator was tested, MACVF, which improves the trend and successfully identifies the most damage-sensitive mode, especially when the maximum level of damage is reached, giving MAC values below 80%. In addition, frequency variations ranged from 70% to 110% when TRM and WWM retrofitting techniques were applied. Full article

As damming material, fine-grained tailings present challenges such as low dam strength and poor stability. To address these issues, this study employs geotextile tube technology to mix water with fine-grained tailings, forming a tailing slurry with a concentration of 60%, which is filled into a geotextile bag to form a geotextile tube, so as to improve the stability of fine-grained tailings. The shear strength characteristics of each interface under different consolidation times and different filling degrees were studied via an indoor shear experiment, including the shear strength of tailing particles, that between tailings and geotextiles, and that within geotextile tubes themselves. The results show that the shear strength of each interface conforms to the Mohr–Coulomb strength criterion, and that the interface cohesion is greatly affected by the consolidation time, while the interface friction angle is mainly affected by the filling degree. Moreover, the shear strength comparison, based on the comprehensive friction angle concept, indicates a substantial increase in shear strength at the interfaces between geotextile tubes compared to both that of the tailings themselves and the interface between tailings and geotextiles, highlighting the reinforcing effect of the geotextile tube filling technology on tailings’ shear strength.
