| 摘 要： | 与钢筋相比 ,FRP材料通常拥有数倍乃至十几倍的强度 ,其它力学性能也有很大的差异。采用FRP材料加固混凝土结构 ,存在诸如破坏形式、延性、极限强度、耐久性等一系列的新问题。在此 ,介绍了目前国外有关FRP加固混凝土结构的设计指南、规程等情况 ,并着重介绍了美国ACI-4 4 0F委员会设计规程 (草案 )中的结构设计概念、设计计算方法及值得注意的一些特点 ,供设计人员参考

| Abstract: | The strength of FRP is several times or even a dozen times plus higher than that of a rebar;other mechanical properties of FRP are quite different.There are many new problems such as failure mode,ductility,ultimate strength and durability etc in the concrete structures strengthened with FRP.The relevant design guidelines and regulations etc of FRP reinforced concrete structures in foreign countries at the present time are introduced with the emphasis on the structural design concept,calculation methods and the characteristics that merit attention of the design regulations (draft) by the American ACI 440 Committee. |
