This paper deals with the equilibrium relationship of bending moments acting on column and restoring force characteristics due to column rocking of traditional wooden frames. From shaking table tests and static lateral loading tests, the interaction between column and bracket complexes or pillow blocks on the top of column and the ambulatory movement of column on the base stone were investigated. The equilibrium relationship between the total restoring force and the sum of the bending moments acting on the column is established. By using this relationship, the restoring force due to column rocking can be estimated. In the total restoring force of traditional wooden frame, the restoring force due to column rocking is distinguished when the frame deformation is small. The restoring force from the bending moments at the column-tie beam joints becomes dominant as the deformation increases. By the collaboration between the restoring forces from the column rocking and the bending moments at the beam joints, the traditional wooden frame demonstrates large flexibility and deformability.
