“…A number of studies have been conducted on FRU structures. [37][38][39][40][41][42] The above merits make FRU composites a form of advanced construction material being used widely for strengthening existing deteriorated structures or building novel structures. [43][44][45][46][47] Preliminary test results on FRU structural elements have brought faith to researchers that FRU is of excellence in mechanical properties and suitable for marine and offshore construction.…”

<p>Offshore floating wind turbines (OFWTs) are gaining popularity due to their superior wind energy capture and minimal visual impact. However, traditional steel support foundations for OFWTs are plagued by corrosion issues. This article proposes the use of Fiber-Reinforced Polymer (FRP) reinforced Ultra-High Performance Concrete (UHPC) composites, referred to as FRU composites, for OFWT foundations. Durability assessment of FRU plates under simulated marine environment is conducted based on accelerated aging tests on FRU plates. Scanning electron microscope (SEM) analyses are conducted to explore the fracture surface and interface between FRP and UHPC matrix. A series of tests are conducted and the test results of the FRU elements are summarized in this article. Strength design methodologies for FRU elements under various loadings are established based on summary of existing studies. Hydrodynamic analyses and comparative studies between FRU and steel OFWTs reveal that FRU OFWTs demonstrate improved stability and reduced motion responses under combined wind-wave-current loading conditions. The successful development of FRU composites is anticipated to revolutionize the OFWT industry by offering durable and cost-effective foundation options.</p>

Ultrahigh performance concrete (UHPC) has recently become a major focus garnering substantial attention due to its remarkable mechanical properties. UHPC has been increasingly employed across diverse projects in the construction industry. However, the structural ductility of UHPC members has yet to be fully established and is often compromised by the manifestation of the crack localization phenomenon. This paper presents the flexural test results of five T‐beams and introduces a model for predicting the flexural capacity and failure modes of UHPC T‐beams. The model employs the curvature ductility index as a measurement for evaluating and ensuring the member's ductility. The results show that the flexural behavior of UHPC T‐beams can be characterized by four key points representing cracking, reinforcement yielding, crack localization, and post‐localization capacity. The validity of the model is substantiated by experimental data from this study and complemented by test data collected from the literature. The proposed model is then employed to derive ductility‐oriented design limits, including minimum and maximum reinforcement ratios and minimum localization strain capacity. Finally, the paper summarizes the design recommendations and provides a classification of section conditions, reinforcement limits, localization strain limits, adequate ductility range, and the feasible ductile design range.
