Special Issue Information

Dear Colleagues,

Fiber-reinforced polymer (FRP)-reinforcing bars and pultruded sections have emerged as efficient and cost-effective materials in civil engineering and construction. Although the general understanding around the FRP bars and pultruded sections has been improved, and their real-life applications has been increased significantly over the past decade, there are still gaps in the knowledge which limits the potential use and applications of these bars and pultruded sections.

This Special Issue aims to highlight the recent developments and applications of FRP bars and pultruded sections. This includes the behaviour of FRP bars both at the material level and structural level. The topics proposed for this Special Issue include, but are not limited to, the following:

  • Modeling, design, manufacture, and application of FRP bars and pultruded sections;
  • Field applications and case studies;
  • Behavior of FRP-reinforced concrete structures and pultruded sections;
  • Durability and long-term performance of FRP bars and pultruded sections under different environmental conditions;
  • Performance of FRP bars and pultruded sections under fire and high temperature;
  • Effects of fibers, resins, and sizing on the physical and mechanical durability of pultruded FRP composites;
  • Bond behavior of FRP bars and pultruded sections in concrete and composites;
  • Creep, fatigue, dynamic, impact, and cyclic behavior of FRP bars and pultruded sections;
  • Structural health monitoring for FRP-reinforced concrete and composite structures;
  • Standards/codes;
  • Life cycle assessment.

Glass-fiber-reinforced plastic (GFRP) composite pipes are used extensively in high-performance applications, due to their high stiffness and strength, corrosion resistance, and thermal and chemical stability. In piping, composites showed high performance due to their long service life. In this study, glass-fiber-reinforced plastic composite pipes with [±40]3, [±45]3, [±50]3, [±55]3, [±60]3, [±65]3, and [±70]3 fiber angles and varied pipe wall thicknesses (3.78–5.1 mm) and lengths (110–660 mm) were subjected to constant hydrostatic internal pressure to obtain the pressure resistance capacity of the glass-fiber-reinforced plastic composite pipe, hoop and axial stress, longitudinal and transverse stress, total deformation, and failure modes. For model validation, the simulation of internal pressure on a composite pipe installed on the seabed was investigated and compared with previously published data. Damage analysis based on progressive damage in the finite element model was built based on Hashin damage for the composite. Shell elements were used for internal hydrostatic pressure, due to their convenience for pressure type and property predictions. The finite element results observed that the winding angles from [±40]3 to [±55]3 and pipe thickness play a vital role in improving the pressure capacity of the composite pipe. The average total deformation of all designed composite pipes was 0.37 mm. The highest pressure capacity was observed at [±55°]3 due to the diameter-to-thickness ratio effect. Full article
