In previous paper, fracture behaviors of notched plate specimens were studied, and the critical values of the COD were established. On the other hand, finite element analysis of notched plates were carried out to evaluate the relationships between the COD and the J-integral. The purpose of this paper is to determine the critical value of fracture of defective structural members after crack propagation and thereby to measure quantitatively the fracture deformability of beam-column connections under cyilic loading. The results of experiments on defective connections are compared with those on notched plate specimens to obtain a relational expression of defect length, deflection amplitude, and hysteresis energy to fracture based on the COD concept in non-linear fracture mechanics.
