Analytical modeling and seismic performance on in-plane behavior of rigid framed steel bridge pier

Rigid framed steel bridge piers had several damages like plate buckling by the attack of the Hyogo-ken Nambu Earthquake. To update seismic design adequately evaluating strength and ductility on in-plane behavior of the pier, some analytical modeling, which can consider plate buckling, is required and is available now but not for practical business use. Then investigated in this study is an adequate modeling method when using beam-column element based on Euler-Bernoulli theory for the analysis and influences of some modeling methods on the seismic performance of the in-plane behavior of the pier.
