| 摘 要： | 在桥塔模型风洞试验的基础上,根据结构驰振稳定性分析方法,对表面平均风压系数进行空间积分,得到侧弯模态广义气动力系数,通过对广义气动力系数随风向角变化的研究,计算得到横风向驰振失稳的各方向来流临界风速,从而确定桥塔的驰振稳定性.

| Abstract: | Based on bridge tower model wind hole experiment,according to method of structure slackening shake stability analysis,it makes special integral calculus for surface average wind pressure modulus,obtains slant bend mode generalized gas dynamic force modulus,according to study generalized gas dynamic force modulus changing with windy direction angle,calculation obtains every direction incident flow critical wind speed of horizontal wind direction slackening shake missing stabilization,consequently to decide slackening shake stability of bridge tower. |
