| 中文摘要: |
| 大跨度桥梁的动力特性是研究桥梁振动的基础，随着跨度的增加，桥梁更加轻型化和柔性化，其几何变形与内力状态地随着风速的改变而变化，从而影响到结构的动力特性，本文介绍了风速变化时大跨径悬索桥动力特性的计算方法，并以广东虎门大桥为例，分析了大跨度悬索桥动力特性随风速度化的规律。 |

| The dynamic behavior of long span suspension bridge is the key to the research of its windinduced vibration and seismic response. Since suspension bridge is a type of geometrical non\|linear structure,its dynamic behavior is closely related to the inner force state.The static wind load would thoroughly change the inner force state of the structure, and consequently change the dynamic behavior.In this paper we explore the influence on the long span suspension bridge by static wind load and put forward our calculation method of the dynamic behavior of long span suspension bridge under static wind load. |
