【摘要】 纤维聚合物(FRP)复合材料因其强度重量比及刚度质量比高、热膨胀系数低、各向异性、轻质、耐腐、无磁、有良好的抗疲劳性能及高耐久性等特点,可广泛应用于桥梁、纤维混凝土、补强加固材料、连续纤维筋、岩土工程和建筑工程中.本文介绍了FRP材料在新建结构、结构加固、桥梁中以及预应力FRP在混凝土结构中的研究和应用状况,并提出了结构用FRP在使用方面的一些问题和开发研究前景.更多还原

【Abstract】 Because of its strength to weight ratio and stiffness weight ratio,low coefficient of thermal expansion,anisotropy,lightweight,corrosion-resistant,non-magnetic,good fatigue resistance and high durability,Fiber Reinforced Polymer(FRP) composite materials were widely used in bridges,fiber reinforced concrete,reinforcement material,continuous fiber reinforcement,geotechnical engineering and construction projects.In our report,the research and application of FRP material in the new structure,structure reinforcement,bridges and prestressed FRP in concrete structures were described,and some problems and prospects were proposed.更多还原
