For train-running safety during earthquake, we should analysis using entire consecutive structures model. When we make the entire structures model, we need yawing stiffness of girder and pier type structures. In this research, firstly we investigated bearing stopper's yawing stiffness of girder and pier type structure by real size test pieces. Secondly we examined pier's yawing stiffness by non-linear numerical analysis considering stopper, pier and pile foundation yawing stiffness. We clarified that initial yawing stiffness depends on pile foundation stiffness, and decline at pier's torsion strength of concrete.
