| 摘 要： | 作为一种新型建筑结构材料，纤维塑料（Fiber Reinforced plastic,简称FRP）在某些特定的条件下可替代传统的木、钢和钢筋材料，具有高强、轻质、抗腐蚀和耐疲劳，温度作用下稳定性好等特点，因而受到土木工程界的关注。本文简要从结构试验、计算理论和计算方法三个方面阐述了国内外研究者对FRP约束混凝土抗震性能的研究现状，并分析了研究中存在的不足。在比较了大量的研究成果之后，基于组成FRP约束混凝土的FRP及其核心混凝土之间组合作用的特点，探讨了FRP约束混凝土抗震性能研究中的若干关键问题。最后，展望了FRP约束混凝土结构抗震性能研究的发展前景。

| Abstract: | As an alternative to timber, steel and steel reinforcement in some special conditions, using of FRP composites is increasingly interested in engineering. The advantages of utilizing FRP in engineering are summarized into higher strength, good resistance to corrosion and fatigue, and greater dimensional and thermal stability. This paper briefly expounds the present situation of the research on the dynamic behaviors of FRP-confined concrete columns from three aspects including structural experiments, calculating method and calculating theory, and analyzes the shortcomings in the research. After comparing many achievements, this paper puts forward several key problems in the research of dynamic behavior of FRP-confined concrete according to the characteristic of composite action between FRP tube and concrete. Finally, the development of the dynamic behavior of FRP-confined concrete structures is prospected. |
