The rotational spring constants calculation methods for segment joints in calculating shield tunnel response values have been organized for bolted joints; however, there has been an increase in the development and construction of segments using joints without bolted connections in recent years. In this study, joint bending tests and finite element analyses were carried out at the stress level at which the joint steel yields, to contribute to modeling the behavior of segment joints beyond the allowable stress level, targeting joints without bolted connections. In this consideration, the gap at the joint surface and the yielding/slip of the joint were extracted as factors influencing joint behavior, and the effect of the joint behavior and its mechanism were investigated.
