POTENTIAL APPLICATION OF UHPC IN COMPOSITE STRUCTURES FOR WIND POWER GENERATION
Abstract
The significant growth in demand for renewable energy in recent years has posed a challenge to structural engineering due to the need for larger and more slender structures to increase generation capacity. Market demands have led to the replacement of steel towers and platforms with reinforced concrete structures, which can incorporate new advanced materials. This paper presents a literature review on the use of ultra-high-performance concrete in mixed structures for onshore and offshore wind energy generation systems. Initially, specific regulatory prescriptions for the use of reinforced concrete in offshore platforms are presented. The properties of ultra-high-performance concrete (UHPC) as well as its applications in energy generation structures are discussed. The results indicate that it is possible to reduce the passive reinforcement of reinforced concrete structures through the use of advanced cementitious materials, and that there is the possibility of applying these materials in steel-concrete composite elements.
