Special Issue Information

Dear Colleagues,

We are pleased to present this Special Issue focused on the research area of fiber-reinforced concrete (FRC) and mortar, as well as fiber reinforced polymers (FRPs), in the design and redesign of concrete and masonry members and structures. This Special Issue aims to bring together innovative research and advancements in the field, covering non-seismic and seismic resistant structures and seismic protection methods, experiments, analyses, and structural interventions. In addition, this Special Issue aims to provide a platform for researchers to share their findings and insights into applying FRC and FRPs in new and existing concrete and masonry structures. FRC and FRPs offer enhanced mechanical properties, durability, and sustainability, making them valuable materials in the construction industry. Topics of interest for this Special Issue include experimental investigations into the mechanical properties of FRC and FRPs, analysis of the structural behavior and performance of concrete and masonry members retrofitted with FRC and FRPs, analytical and numerical modeling of FRC and FRP retrofitting techniques, and assessment of the seismic response and performance of structures.

Additionally, this Special Issue welcomes research on non-seismic and seismic resistant structures, exploring different methods for seismic protection and developing innovative strategies for structural interventions. Case studies and practical applications of FRC and FRPs in new and existing structures will also be considered. The publication of this Special Issue will contribute to the advancement of knowledge in the field of FRC and FRPs, providing valuable insights for researchers, engineers, and professionals involved in the design and retrofitting of concrete and masonry structures. It is anticipated that the collection of articles within this Special Issue will inspire further research, foster collaborations, and promote the adoption of sustainable and resilient construction practices. Therefore, we invite researchers and experts in the field to submit their original research papers and case studies for consideration in this Special Issue. Manuscripts will undergo a rigorous peer-review process to ensure the quality and relevance of the published work.

We look forward to receiving valuable contributions that will further enhance our understanding and application of FRC and FRP in designing and redesigning concrete and masonry members and structures.

Easy maintenance and high durability are expected in structures made with fiber-reinforced cementitious composite (FRCC) reinforced with fiber-reinforced polymer (FRP) bars. In this study, we focused on the bond and cracking characteristics of polyvinyl alcohol (PVA)-FRCC reinforced with braided AFRP bars (AFRP/PVA-FRCC). Pullout tests on specimens with varying bond lengths were conducted. Beam specimens were also subjected to four-point bending tests. In the pullout tests, experimental parameters included the cross-sectional dimensions and the fiber volume fractions of PVA-FRCC. A trilinear model for the bond constitutive law (bond stress–loaded-end slip relationship) was proposed. In the pullout bond test with specimens of long bond length, bond strength was found to increase with increases in both the fiber volume fraction and the cross-sectional dimension of the specimens. Bond behavior in specimens of long bond length was analyzed numerically using the proposed bond constitutive law. The calculated average bond stress–loaded-end slip relationships favorably fitted the test results. In bending tests with AFRP/PVA-FRCC beam specimens, high ductility was indicated by the bridging effect of fibers. The number of cracks increased with increases in the fiber volume fraction of PVA-FRCC. In specimens with a fiber volume fraction of 2%, the load reached its maximum value due to compression fracture of the FRCC. The crack width in PVA-FRCC calculated by the predicted formula, considering the bond constitutive law and the fiber bridging law, showed good agreement with the reinforcement strain–crack width relationship obtained from the tests.
