Bridge Safety Assessment Based on Complex System Theory and Nonlinear Time Series
Jianxi Yang, Lizhang Qian and Qingyang Liu

Abstract:
This study presents a method of safety assess of existing bridges based on Complex System Theory and Nonlinear Time Series. Bridge Structure System has characteristics of complex system. Such as dissipation, fractals, chaos and so on. Chaotic nonlinear time series of monitoring information of ASCE Benchmark and Masangxi bridge. By G-P and C-C algorithms to extract the largest Lyapunov Exponent and Embedding Dimension. The results showed that: the structural system of Correlation Dimension greater than2 and not an integer, the largest Lyapunov Exponent is greater than 0, Indicating that the systems exist Chaotic Phenomena. So, Complex System Theory is using for bridge system.
