| 英文摘要 | In order to study the fracture behavior of three-graded concrete under cyclic loading after initial static loading, the three-point bending test of three-graded concrete beam is carried out in this paper. In the course of loading, acoustic emission (AE) and 3D digital image correlation (3D DIC) are used to record the AE signal and surface crack of concrete beam under dynamic load. And the damage evolution behavior of three-graded concrete beams is described quantitatively based on the results of AE and DIC. The results show that the damage indexes of AE hits and crack opening area are in good agreement with that of Secant Modulus of P-CMOD curve of beams under three-point bending, which can be used to quantitatively characterize the damage degree of concrete. In addition, by comparing the crack morphology and fracture surface characteristics of three-graded concrete, the crack propagation mechanism of three-graded concrete with different loading frequencies is analyzed. |
