Fiber Reinforced Polymer-Ultra High Performance Concrete (FRP-UHPC): Design, Performance, and Application

Dear Colleagues,

Recent advances in ultra-high-performance concrete (UHPC) represent transformative developments in material engineering. Researchers and practitioners increasingly prioritize UHPC due to its unparalleled capacity to enhance structural performance, extend infrastructure service life, and reduce lifecycle costs. The integration of fiber-reinforced polymer (FRP) with UHPC has emerged as a prominent research focus owing to synergistic performance enhancements. For instance, FRP minibars significantly increase the strength and toughness of UHPC while eliminating corrosion risks and fiber segregation associated with conventional steel fibers. Furthermore, FRP-UHPC systems reduce carbon emission of marine construction by incorporating unprocessed seawater and saline sea-sand as functional constituents.

This Special Issue, titled “Fiber Reinforced Polymer-Ultra High Performance Concrete (FRP-UHPC): Design, Performance, and Application”, addresses essential aspects of FRP-UHPC systems, encompassing design principles, material/structural performance, and infrastructure applications. Tackling contemporary challenges requires comprehensive technical insights spanning from laboratory experimentation to field implementation. This Special Issue emphasizes cutting-edge advancements in FRP-UHPC system design, performance, and applications, including constituent design, mechanical performance, durability, structural performance in new construction and strengthening applications, and lifecycle carbon emissions.

This Special Issue synthesizes transformative research and practices to catalyze academic discussion on critical gaps in technology of FRP-UHPC systems. These insights will help solve real-world problems and promote development and application of FRP-UHPC systems, ultimately advancing sustainable infrastructure.

Potential topics include, but are not limited to, the following:

• FRP minibar-reinforced UHPC: Strength, toughness, stress–strain behavior, creep, shrinkage, crack resistance, and durability;
• Marine applications of FRP-UHPC systems: Seawater/sea-sand UHPC and offshore structures;
• FRP-UHPC composite structures;
• Structural design of FRP bar-reinforced UHPC members;
• FRP-UHPC system performance under extreme environments: Elevated temperature, blast/impact loading, marine exposure, electrical exposure, electrochemical corrosion, seismic actions, and other single/multifactor conditions;
• Data-driven design methodologies: Machine learning, deep learning, and AI for FRP-UHPC system optimization;
• Applications of FRP-UHPC system in repair/strengthening;
• Case studies: Bridges, marine installations, high-rise buildings, and critical infrastructure demonstrating FRP-UHPC implementation.

Original research papers and review articles are welcome. Submission to this Special Issue is open to all interested parties, both those who are interested in the subject topics and those who are invited.

We look forward to receiving your contributions.
