Study on Multifractal Characteristics of Acoustic Emission Sequence of Concrete with Different Steel Fiber Content under Uniaxial Tension

In order to reveal the relationship between acoustic emission signal characteristics in concrete with different steel fiber contents and damage evolution law under uniaxial tension, the standard multifractal method and multifractal detrended fluctuation analysis (MF-DFA) are used to analyze the multifractal characteristics of the acoustic emission hit rate. The results show that: (1) the inner fluctuation of the acoustic emission sequence is a well-regulated multifractal, which is a long-range correlated process determined by intrinsic self-similar properties; (2) with an increase of steel fiber content, the acoustic emission time series is more persistent and the long-range correlation of the acoustic emission signal is longer; and (3) the local Hurst exponent can be used as a parameter for the early warning of steel fiber reinforced concrete failure.
