摘要
FRP约束混凝土和钢管混凝土是两种不同的约束混凝土应用形式,分析表明,对混凝土进行约束,可以提高其承载力和延性;FRP约束下核心混凝土强度提高幅度较大;钢管混凝土构件延性好,破坏时变形较大,而FRP混凝土构件破坏呈脆性,破坏时变形较小,破坏发生突然。
FRP-confined concrete and concrete-filled steel tube are two specific applications of confined concrete. Analysis shows that by restraining concrete, its load capacity and ductility can be improved and the core concrete under FRP restraint is strengthened considerably. It also shows that concrete-filled steel tubular member has bigger deformation at failure due to its good ductility while FRP concrete member fails abruptly, presenting brittleness with less deformation.
