| 中文摘要: |
| 大型钢制桥塔其风振特点与常规混凝土桥塔有较大差异，国内有关钢桥塔风振研究较少。通过对钢桥塔横风向驰振传统计算方法的简单论述，指出了传统计算方法的不足之处，提出了考虑非准定常效应计算驰振响应的方法。 |
| 英文摘要: |
| There are great differences in the vibration characteristics induced by wind between large steel bridge tower and concrete bridge towers. However, the domestic studies on wind induced vibration are few. With a simple exposition of traditional calculation method considering the cross wind galloping of steel bridge tower, the inadequacy of the method is pointed out. Then, a new method calculating the galloping responses, which considers the effect of non quasi steady, is put forward. |
