The present study aims at developing a practical evaluation method for the ductile crack initiation in steel bridge piers, which is the first step of brittle fracture. For this purpose a damage index based on the analysis using the shell element has been proposed by the authors. In this paper, as a practical application to seismic design of steel bridge piers, a damage index considering strain concentration is newly proposed for fiber analysis using the beam element. Comparisons between the prediction and experimental data showed that by applying the presented method, the ductile crack initiation can be accurately predicted.
