摘要：
The dynamic characteristic of cable damage is calculated of Tianxingzhou long-span cable-stayed bridge. Firstly, a normalized natural frequency is defined and the affection of cable damage on normalized natural frequency is analyzed. Through comparative studies came to the following conclusion: the damage effect on the natural frequencies of different levels of cable mode are essential differences, thus establishing a description of cable damage model based on support vector machine, the different damage cases are used to train and recognize. The numerical example shows that the method can be effectively used to identify the damage of cable of long-span cable-stayed bridge.
