| 南京大勝關(guān)長江大橋鋼吊桿兩端連接渦振疲勞性能的仿真分析(51 卷) |
| 英文標(biāo)題 |
| Simulation analysis of vortex-induced vibration in connection of steel suspender ends of Nanjing Dashengguan Yangtze River Bridge |
| 摘要 |
| 建立了南京大勝關(guān)長江大橋主橋鋼桁拱吊桿整體及兩端連接節(jié)點(diǎn)局部的有限元模型，分別對H形和切角矩形兩種截面吊桿在渦振作用下節(jié)點(diǎn)處構(gòu)造細(xì)節(jié)的疲勞性能進(jìn)行了仿真分析，研究了不同截面形式吊桿兩端節(jié)點(diǎn)的疲勞性能。研究結(jié)果表明鋼拱橋吊桿渦振時(shí),其兩端連接節(jié)點(diǎn)極易出現(xiàn)疲勞 |
