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