Additionally, irregular external excitations, such as earthquakes, cause damage to the structures, thereby decreasing the original performance of structures and leading to changes in their natural frequency and damping characteristic. In this study, we have constructed an earthquake resistant design in accordance with the specifications for highway bridges (2012 edition) for a single RC bridge pier and presented the M-Φ relationship for a specific pier base to allow the description of the M-θ relationship of the rocking SDOF model. Furthermore, we have carried out a nonlinear response analysis and performed the characteristic extraction of the acceleration wave pattern using the discrete wavelet transform using a scale function and the wavelet spectrum that was the summation of the wavelet Fourier spectrum for each resolution factor. In addition, the input earthquake motion and acceleration waveform to be used for the dynamic analysis in the seismic design of the road bridge of the Japan Road Association, using the observation record that became the original.
