Abstract: In this study, the acoustic emission method was applied to clarify the fracture process of concrete. The effects of loading method and support condition on the fracture behavior of concrete subjected to the pull-out loading of anchor bolt were discussed experimentally and analytically by paying attention to the crack propagation in a specimen. Following results were obtained in this study : 1) Kaiser effect is recognized in the cyclic pull-out loading of anchor bolt, but is recognized unclearly in the loading level that the non-linear behavior of P-δ relation is remarkable and then the macroscopical crack is observed. 2) The fracture process of concrete subjected to the pull-out loading can be predicted by using the AE source location search technique. 3) The shape of P-δ relation obtained by the cyclic loading is more brittle than that obtained by the monotonic loading. 4) The fracture process of concrete subjected to the pull-out loading can be predicted by the finite element method considering the tensile crack by a smeared failure model.
