| 大跨鋼桁架梁氣動選型及氣動參數風洞試驗研究(50 卷) |
| 英文標題 |
| Aerodynamic type-selection and aerodynamic parameters test study at wind tunnel for large-span steel truss girder |
| 摘要 |
| 以一大跨懸索橋——壩陵河大橋鋼桁梁主梁斷面為研究對象，通過節(jié)段模型風洞試驗和高頻動態(tài)天平測力試驗，得到了鋼桁梁主梁優(yōu)化斷面并試驗得出三分力系數、顫振導數以及氣動導納，歸納出適合鋼桁梁橋梁斷面的氣動導納經驗公式，改善了傳統上計算抖振在氣動導納上的明顯缺陷。 |
