| Abstract: | The natural vibration property,the internal force in the seismic response spectrum and the elasto-plastic seismic response are analyzed based on a long-span reinforced concrete arch bridge considering the effect of initial internal force.The analysis indicates that the effect of initial internal force to the natural vibration frequency and the seismic response of the bridge is very limited,and the aseismic performance of the bridge is excellent. |
