In order to expand the scope of application of the newly proposed analysis method using equivalent plastic displacement at element failure proposed by the authors, a fracture analysis was performed on experimental specimens of steel bridge piers with unstiffened box section subjected to random cycle displacement s. As a result, both the crack initiation and propagation of the experiment could be accurately simulated. In addition, the same analysis was performed even with a small mesh size, and the difference in the mesh size was confirmed. When the mesh size was made smaller by about half, the analysis time increased by about 4 times, but there was no significant difference in the crack initiation and propagation.
