Comparison of time history curves of acceleration. Note: 0.25-1-R stands for the radial acceleration time history curves of the top of pier #1 when the input peak acceleration of seismic wave was 0.25 g PGA; 0.25-1-T stands for the tangential acceleration time history curves of the top of pier #1 when the input peak acceleration of seismic wave was 0.25 g PGA and similar to other circumstances.
