In this paper, structural behaviors of anchor systems subjected to shear loads are analyzed by using fracture analysis and experiments. Two dimensional finite element analyses of concrete anchor systems to predict breakout failure of concrete through progressive fracture are carried out by utilizing the so-called embedded crack model. Three dimensional finite element analyses are also carried out to investigate the fracture behavior of anchor systems having different effective lengths, edge distances, spacings between anchors, and direction of loads. Results of analyses are compared with both experimental results and design values of ACI code on anchor, and then applicability of finite element method for predicting fracture behavior of concrete anchor systems is verified.
