Abstract

A steel bridge pier cross section, which is consisted of comparatively thick wall and is stiffened by less number of stiffeners, is proposed from the view of seicemic capacity and construction costs. At first various cross-sections are designed and evaluated from the view of costs. Then, tests and analysis are undertaken to evaluate the seicemic capacity of proposed structures. The test specimens were cantilever steel box columns, modeling one-tenth scale steel bridge piers. Cyclic loading tests and on-line tests, simulating real earthquake response, were done on the specimens. Analysis was also done for the various cases of earthquakes and weight of superstructures. The steel bridge piers are proved to have enough seicemic capacity.
