Continuous fiber reinforcing materials(CFRM) are given attension as a new highquality reinforcing orprestressing material for concrete structures. The purpose of this study was to establish design procedures for concrete structures with CFRM.The main results were obtained from the following investigations.1) Variation properties of tensile strength of CFRM of carbon, aramid and glass fibers, neccessary number of specimens to determine the characteristic strength of CFRM, relation between elastic moduli of CFRM and stress levels, bond properties of CFRM, and creep properties of CFRM were investigated.2) Ultimate moment of concrete beams with CFRM main reinforcement, ultimate shear force of beams with CFRM main reinforcement and with or without CFRM shear reinforcement, and ultimate shear force of prestressed concrete beams with CFRM tendon were investigated.3) Minimum main reinforcement of beams with CFRM, and improvement of ductility and capacity of moment redistribution of beams by confinement of concrete with CFRM were investigated.4) Deflection and crack width of beams with CFRM were investigated.5) Prestressed concrete with CFRM external cable, strengthening of damaged reinforced concrete by prestressing with CFRM external cable, and chemically prestressed concrete with CFRM were investigated.

连续纤维增强材料(CFRM)作为一种新型的高性能混凝土结构加固或预应力材料，受到了人们的重视。本研究的目的是建立CFRM混凝土结构的设计程序。主要研究结果如下：1)碳纤维、芳纶和玻璃纤维CFRM抗拉强度的变化特性，确定CFRM特征强度所需的试件数量，CFRM弹性模量与应力水平的关系，CFRM的粘结性能，CFRM的徐变性能。2)CFRM主筋混凝土梁的极限弯矩，CFRM主筋配筋和CFRM主筋配筋的极限剪力，以及CFRM筋的预应力混凝土梁的极限剪力。4)研究了CFRM加固梁的挠度和裂缝宽度。5)研究了CFRM体外索预应力混凝土、CFRM体外索预应力加固受损钢筋混凝土和化学预应力CFRM加固钢筋混凝土。
