| 摘 要： | 悬索桥服役一段时间以后,在风荷载的作用下将造成主要构件加劲梁抗弯刚度的削弱进而导致结构损伤。对悬索桥的主要构件加劲梁进行分析,得出加劲梁在侧向风荷载作用下的振动特性,并利用损伤结构柔度差值曲率的变化对其进行损伤识别。

| Abstract: | After a period of service time,the moment rigidity of the stiffening beam for a suspended bridge will be impaired under the wind load,which will lead to the structural damage.By investigating the stiffening beam which is the main component of the suspended bridge,the vibration characteristics under the lateral wind loads are obtained.The damage identification is conducted using change in the flexibility difference curvature. |

| Keywords: | suspended bridge stiffening beams vibration characteristic flexibility difference curvature damage identification |
