摘要
介绍了纤维增强聚合物混凝土组合材料的发展状况及工作机理 ,指出FRP混凝土构成的组合构件既发挥了FRP和混凝土各自的优势 ,又能通过该 2组分的协同作用满足结构工程对强度、刚度、耐久性、延性、耐腐蚀性及综合造价的要求 .基本力学性能计算表明 ,FRP管混凝土的抗压强度和延性成倍提高 ,受拉时开裂延缓 ,经过合理设计的组合梁、柱等构件具有极佳的抗震性能 .
The paper presents the development of fiber reinforced polymer(FRP) confined concrete combined materials and reveals the working mechanism of FRP confined concrete. The combined components have advantages of both FRP and concrete. They can meet the needs of structure engineering for strength, toughness, durability, ductility, corrosion resistance and overall costs. The calculation of its basic mechanical properties shows that the compressive strength and ductility of FRP confined concrete increase dramatically and the cracking upon tension is delayed. The combined components of beams and columns designed properly have optimum aseismatic performance.
