The static cyclic test of the column specimen was conducted. To observe the behavior of the column of the arch bridge under the seismic excitation exceeding the design earthquake ground motion, the two-directional horizontal displacements and axial force were controlled based on the results of the dynamic analysis of the arch bridge system. The geometrical data of FE model of the test specimen, including the initial imperfection, were calculated by using its point cloud. Comparing the strain distribution measured by the digital image correlation (DIC) technique, it is confirmed that the FE analysis simulated not only the forcedisplacement relation but also the deformation of the test.
