About this Research Topic
In recent years, the need for more sustainable, resilient and economical reinforced concrete (RC) structures has enabled the application of advanced materials through research and practice. Fiber-reinforced polymers (FRPs), which are typically used in construction due to advantages such as light weight, high strength, and excellent anti-corrosion properties, have emerged as a popular material in new RC structures as well as in strengthening, retrofitting, or repairing existing RC structures. Even though some documented results have been achieved, the problems of using FRPs in the construction of concrete structures have not yet been fundamentally and conclusively resolved. One of the most critical issues is the low ductility of FRP-concrete structures, which has attracted the increasing attention of the research community.
The application of advanced materials for more sustainable, resilient, and ductile RC structures has attracted extensive interest of the research community in recent years. The developed technologies in producing FRP products and the lowering cost of FRP materials contribute to their potential use in construction. However, the ductility problem should be resolved before the use of FRP in construction. The main objectives of this Research Topic are to collect, distinguish, as well as highlight some of the most recent developments in this area to allow for comparative studies of proposed advances, and to document future research needs.
The Research Topic focuses on fundamental knowledge that advances the state-of-the-art and state-of-the-practice in enhancing the ductility of FRP-concrete structures. Manuscripts published in the Research Topic are expected to reflect original research and technological advances on topics that include, but are not limited to, the testing, analysis, and design of new structures as well as the repair, retrofit, and strengthening of existing concrete structures using:
• FRPs in forms of bars, sheets, plates, tubes, etc.
• steel FRP composite bars (SFCBs)
• FRP in combination with ductile reinforcement
• FRP in combination with non-traditional cementitious materials
