Summary:The static tests of the column specimens were conducted in order to evaluate the residual structural performance of the columns of steel arch bridges. The twodirectional horizontal displacement and vertical force acting the specimen as seismic excitations were conducted by using the dynamic analysis of the arch bridge model. Compared with the specimens without seismic excitation, the displacement at the maximum strength under the one-directional cyclic loading was reduced despite almost same strength. This tendency was simulated by the FE analyses with constitutive equation we newly developed.
