摘　　要：利用我国自主开发的FRP复合筋加工混凝土梁式构件,采用两点加荷方式进行了弯曲试验,测定了单调荷载作用下的梁的挠度与相应的荷载关系曲线,研究了配筋率、与混凝土的粘接作用等因素对构件承载能力、变形性能的影响,分析了FRP筋混凝土梁在荷载作用下的变形特征和破坏形态,提出了FRP筋混凝土梁设计方法。Utilizing FRP complex bar developed independently by China to process beam type construction member of concrete, it has adopted two points loading method to conduct flexural test, measuring deflection and corresponding load relation curve of beam under simple load action, researching influence of factors of ratio of bar arrangement, adhesive bonding action with concrete, etc. to loading capacity and deformability of construction member, analyzing deformation characteristics and destruction form of FRP bar concrete beam under load action, deriving calculation formula for loading capacity of FRP bar concrete beam, putting forward design method for FRP bar concrete beam. It has supplied reference for engineering technical personnel to conduct FRP bar concrete structural design, construction and formulating of corresponding norm.
