In the seismic design against large scale earthquakes, it is necessary to obtain the response calculated through dynamic nonlinear analysis. On the other hand, the dynamic behavior of structure changes according to material characteristics and the strength of structural members at earthquake. Moreover, the characteristic of RC column of rigid frame viaducts changes in correspondence with the axial force. In this paper, the influence of these factors on seismic performance was examined.
