Introduction Even many new materials have been developed in recent years, carbon steel is still one of the most widely used materials in engineering, because of its good properties of processing and low cost.
Materials and experimental procedure The materials used in this study are three kinds of medium structural carbon steels, JIS S25C, S35C and S45C.
The S-N curves of S35C are shown in Fig. 2, and Fig. 3 is the fatigue limits of all the test materials.
All of the fatigue limits of the three kinds of materials increase with the increasing of tensile pre-strain ratio.

Study on State Recognition of ASCE Benchmark based on Lyapunov Exponent Spectrum Entropy Jianxi Yang1,a, Jianting Zhou2,b and Yue Chen3,c 1School of Information Science and Engineering, Chongqing Jiaotong University Chongqing, PR.China, 2Institute of Civil Engineering, Chongqing Jiaotong University Chongqing PR.China, ayjx@cquc.edu.cn, bJt_zhou@163.com,c253500184 @qq.com Key words: ASCE Benchmark; Chaos; Time-series; Lyapunov Exponent; Lyapunov Exponent Entropy; Security Evaluation Abstract: The paper has made a maximum Lyapunov exponent and Lyapunov exponent spectrum entropy analysis of ASCE Benchmark using non-linear theory and chaos time sequence.
However, such mission is hard to achieve as the bridge exhibits complex non-linear behavior as a result of the non-linearity of the bridge internal structure, the component materials as well as the external random influences.
