Abstract
Pseudo-dynamic tests were performed using six cantilever steel box columns with or without longitudinal stiffeners in order to investigate the behavior of real steel bridge piers under severe earthquakes. Three different artificial earthquake motions of level 2 are used which have been developed by Public Works Research Institute in Japan.
Among the three types of ground motion, the type I ground motion is found to be the severest to the steel bridge piers though the maximum acceleration is the smallest.
