摘要
对近年在土木工程领域开始应用的碳纤维复合材料CFRP(Carbon Fiber Reinforced Polymer)的物理力学性能作了介绍,并与钢绞线的力学性能进行了对比,通过算例,分析了配置碳纤维(CFRP)吊杆和系杆的大跨混凝土系杆拱桥力学性能,可以看到CFRP材料在大跨混凝土系杆拱桥中是一种很有发展前途的新型材料。
In this present paper, the material properties of carbon fiber reinforced polymer (CFRP), which has been newly developed in civil engineering, is introduced, followed by a comparison with regular steel strand. The mechanical behavior of long span concrete arch bridge with CFRP hangers and tie bars is analyzed through examples. Results of the analysis demonstrate that CFRP is a promising material for applica tion of the bridge.
