| 南京大胜关长江大桥钢吊杆两端连接涡振疲劳性能的仿真分析(51 卷) |
| 英文标题 |
| Simulation analysis of vortex-induced vibration in connection of steel suspender ends of Nanjing Dashengguan Yangtze River Bridge |
| 摘要 |
| 建立了南京大胜关长江大桥主桥钢桁拱吊杆整体及两端连接节点局部的有限元模型，分别对H形和切角矩形两种截面吊杆在涡振作用下节点处构造细节的疲劳性能进行了仿真分析，研究了不同截面形式吊杆两端节点的疲劳性能。研究结果表明钢拱桥吊杆涡振时,其两端连接节点极易出现疲劳 |
