| 摘 要： | 为研究特大跨度碳纤维索(CFRP)斜拉桥的抗震性能,以主跨为1700m的钢斜拉桥为例,运用三维非线性有限元理论进行抗震性能分析。分析结果表明,特大跨度斜拉桥采用碳纤维索后:(1)减小了桥梁的最大内力值,改善了结构的受力状态;(2)桥梁的变形特征基本接近。因此,从抗震性能方面考虑,特大跨度斜拉桥采用碳纤维索是可行的,斜拉索截面的确定建议采用等刚度的方法。

| Abstract: | To understand the seismic stability of carbon fiber reinforced polymer(CFRP) cables for cablesupported bridges,based on a cable-stayed bridge with main span of 1 700 m,cable-stayed bridges with CFRP stay cables are designed,in which the cable's cross-sectional area is determined by the principles of equivalent cable strength and stiffness,by using the 3D nonlinear finite element analysis,seismic behavior of the cable-supported bridges are numerically investigated.The results shows that:(1)compared with the ... |
