This paper presents a relationship between the seismic response and the curvature at the bottom of the pier, based on the principle of Pushover method. The formula to calculate the critical angle is gained in the paper with non-liner Pushover method. Through a case of curved bridge, the critical angle in the seismic response of curved bridges is calculated with the non-linear statical analytical method. The formula is accurate as it is compared to the results of 0-180 degree dynamical time history analysis. According to the formula, it makes sense in the engineering project to use Pushover method to find the critical angle to the seismic response of curved bridges.
