摘要
This article analyzes characteristics of bridge structure and possibility of occurrence of chaos of structure under intense loads during operation period then, Using the method of Melnikov analyzed the chaos' critical state appearing in vibration formula of bridge structural system. The paper puts forward to the chaos index, such as correlation dimension, the Maximum Lyapunov exponent, etc. The relevant dimensions are all greater than 2 and are not integer and the max Lyapunov index is also greater than 0. These have fully proved that the bridge under vibration appears chaos phenomena.
