【摘要】 纤维增强塑料(FRP)以其抗拉强度高、质量轻、耐腐蚀、易于加工等特点而倍受土木工程界的关注,在工程中有着广泛的应用.在阅读大量国内外相关文献的基础上,首先简要介绍了FRP发展的历史,着重从加固机理、应力-应变关系曲线、强度模型、偏心受压、抗震、耐久性等方面阐述了FRP约束混凝土柱的发展现状.最后指出在FRP约束混凝土柱中存在尺寸效应.讨论了在FRP加固混凝土柱的研究中还没有解决的尺寸效应问题.更多还原

【Abstract】 The Fiber Reinforced Plastics(FRP) has aroused concern for its property of good strength,small density,anti-corrosion and easiness to processing etc.It has been widely used in civil engineering.Based on a large amount of literature in the relevant field at home and abroad,the paper introduces the history of FRP development simply,and puts the emphasis on describing the development status of FRP reinforced concrete column in terms of reinforce mechanism,stress-strain curve,intensity model,eccentric compression,seismic fortification and durability.Finally,the author puts forward that there is a size effect in the FRP reinforced column,and discusses the size effect which has not been solved during the research of FRP reinforced concrete column.更多还原
