Based on the example, red-Flag Bridge in Chongzhou City, using the finite element to analyze the response spectrum of seismic performance for the concrete arch bridge under two conditions. Through the numerical analysis of vibrational damage on the whole bridge, reveals the nether structure and elements of bridge is affected by the seismic waves under the seismic effect and the great stiffness in upper structure, and posts that the anti-inertia in longitudinal direction is more powerful than the transverse and vertical ones. The deformation of arch ring is mostly affected by the displacement on transverse line, DY direction, and less in the longitudinal, vertical and rotational direction. According to the analysis of spectrum value displacement on abutment, finds out that the transverse direction of abutment is mostly affected by the displacement on DZ direction, for the abutment displacement, less in the middle, big in both sides. And for the vertical one, it is mostly affected by DY displacement, in the DY displacement of abutment, big in top, less in base.
