摘要
纤维增强复合材料(Fiber Reinforced Polymer,简称"FRP")具有轻质高强、耐腐蚀、耐疲劳和低导热系数等优点,现已广泛应用于土木工程各领域。针对FRP约束钢筋混凝土结构的抗爆性能,通过综述近年来国内外爆炸荷载下FRP约束钢筋混凝土结构动力响应的研究现状及进展,表明FRP材料的约束对钢筋混凝土结构的抗爆性能有显著的提高作用。此外,从相关理论研究、试验研究和数值模拟3个方面介绍了主要成果。针对现有成果,对爆炸荷载下FRP约束钢筋混凝土结构动力响应研究提出了需要进一步研究和解决的问题,可为后续研究提供一定的参考。
Fiber reinforced polymer (FRP) has been widely used in civil engineering with the advantages, such as high strength to weight ratios, corrosion resistance, fatigue resistance, low thermal conductivity and so on. This study focuses on the blast resistance of the reinforced concrete (RC) structure confined with FRP. By reviewing the research on the dynamic responses of the reinforced structure confined with FRP under blast loads, it is found that the blast resistance of RC structure has been significantly strengthened by the confinement of FRP. Additionally, primary results are introduced from the three aspects, such as the theoretical research, experimental research and numerical analysis. Based on the existing achievements, both valuable research issues and suggestions are presented, which could provide a certain reference for the future research.
