摘　　要：由于普通钢筋混凝土梁基于钢筋屈服的延性分析方法不能直接用于仅配纤维塑料筋(FRP)的混凝土梁,通过分析国内外有关FRP筋混凝土梁的研究成果,引入了一种针对FRP混凝土梁的基于能量的延性定义,并给出了“延性比”的能量表达式。该定义同时适用于普通钢筋混凝土梁的延性分析。Conventional measures of the ductility based on the yielding of steel bar could not directly apply in the concrete beams that containing only fiber reinforced plastics （FRP） bars. By analyzing Chinese and overseas research results of concrete beams reinforced with FRP bars, the definition of the ductility based on energy of concrete beams reinforced with FRP bars was introduced, and the energy formulation of ductility ratio was got. The definition could also be applicd in conventional concrete beams.
