Study of the Bond-Slip Behavior between Rebar and Concrete Based on Acoustic Emission Technology
应用声发射技术的钢筋与混凝土粘结滑移特性研究

In order to study the bond-slip characteristics between rebar and concrete,pull-out experiment was carried out for reinforced concrete specimens with different bond length,meanwhile,pull-out comparative experiment for specimens with the same bond length but different shapes of embedding reinforcing steel bar was also carried out.Corresponding waveform signals were collected by using acoustic emission technology,and then wavelet denoising and Gabor wavelet time-frequency analysis were carried out for the acq...
