Abstract
The present paper describes the damage state and redundancy of steel piers sustaining highway bridges under specified or unthinkable earthquake. The redundancy factor is introduced for measuring their seismic performance. This factor is given by the ratio of the standard horizontal seismic factor, i.e., earthquake strength coinciding with their horizontal capacity, to the horizontal seismic factor defined by the Japanese Specifications for Highway Bridges. Their safety level can be classified by this factor. The damage state and redundancy of steel bridge piers are determined by using their structural characteristics obtained by the elastic-plastic finite displacement analysis. The thin-walled steel box piers stiffened longitudinally are targeted, and are analyzed by general purpose finite element program MARC2012.10. As a result, is classed what damage state a bridge pier would end with under unthinkable earthquake by the equal-energy approach. The damage degree of steel bridge piers are given by a combination of horizontal capacity and horizontal displacement.
