【摘要】 纤维增强复合材料(FRP)以其轻质高强、耐腐蚀、耐疲劳、施工方便等特点,备受土木工程界内人士的关注.近年来随着国内外对FRP材料的研究和发展,FRP作为一种高效的、极具发展和应用前景的新型建筑材料其应用也日益广泛,现己成为结构补强加固和新结构体系开发中的一种重要的新材料.本文主要从FRP加固混凝土柱应力-应变关系,抗震性能以及数值模拟等方面对FRP加固混凝土柱的国内外研究状况进行详细阐述.更多还原

【Abstract】 Fiber reinforced polymer(FRP) is attracting a lot of attention from civil engineers for its light weight,high strength,high corrosion resistance,anti-fatigue,and easy construction.In recent years,with the research and development of FRP materials at home and abroad,FRP,as a new type of building material with bright development and application prospects,has been increasingly used.It is an important new material used for structure reinforcement and strengthening,and new structural system development.This paper expounds on the research status quo of FRP strengthening concrete columns,at home and abroad,in terms of stress-strain relationship,anti-seismic performance,and numerical simulation.更多还原
