Abstract：In order to improve the rationality of design of large size reinforced concrete members
strengthened with fiber reinforced polymer（FRP），the size effect covering large size of reinforced
concrete structures strengthened with FRP should be considered. The state-of-the-art of studies
on size effect of reinforced concrete structures strengthened with FRP was summarized and
analyzed. The study results of size effect on FRP materials, bonding strength of FRP
and
concrete，concrete beams strengthened with FRP and reinforced concrete columns strengthened
with FRP were introduced emphatically. Based on the summaries of previous research, advices
for advanced research on size effect on FRP reinforced concrete structures were provided.
Key words: fiber reinforced polymer；reinforced concrete member；size effect；bonding property ;

引 言
新建结构中得到了越来越广泛的应用02,如美国
Texas Hamilton 饭店,部分柱子采用了 FRP 进行
纤维增强复合材料(Fiber Reinforced Polymer，
了维修加固,在日本利用FRP对一般建筑物和桥梁
FRP)由于具有轻质、高强、耐腐蚀、抗疲劳等许多优
进行加固分别占到了总加固量的45%和 40%;在各
异的性能而逐渐得到了研究者和土木工程师们的认
种新建结构中,FRP的应用形式主要以FRP筋、各
可与青睐。近年来,FRP在既有建筑的修复加固和
种类型的型材及混凝土添加料为主。FRP混凝土
