| 摘 要： | FRP筋的线弹性力学性能导致FRP筋混凝土结构延性较差,因而FRP筋混凝土结构的延性已成为其应用中最受关注的问题之一.本文通过对FRP筋混凝土梁的位移延性、曲率延性、能量延性及综合性能指标的试验研究,指出了适合FRP筋混凝土构件的延性计算方法.

| Abstract: | The ductility of structure reinforced with FRP rebars becomes a main concern,because the concrete members with FRP rebars are lack of ductility due to the linear elastic behavior of FRP rebar up to failure.After the deflection ductility,curvature ductility,energy dissipation capacity and overall performance factor of beams are studied,the overall performance factor is suggested to serve as the scale for evaluating the ductility,which is proven by evaluating specimens in the paper. |
