Local buckling analysis of steel bridge pier under cyclic loading

Yamaguchi, E. / Goto, Y. / Hayashi, M. / Kubo, Y.

After the 1995 Hyogo-ken Nanbu Earthquake, much research is conducted in Japan so as to improve the seismic performance of steel bridge piers. In the present study, we deal with a steel bridge box pier with round corners, which is often employed in an urban area from an aesthetic viewpoint. In particular, we conduct the large deformation analysis of this bridge pier by the finite element method. For constitutive relationships, the three-surface model as well as the conventional J₂-plasticity model is utilized. The analyses reproduce the local buckling near the lower end of the pier. The comparison of the numerical results with experimental data confirms the validity of the three-surface model for the analysis of a steel bridge box pier with round corners.
