Abstract
For a box sectional steel column with transversely profiled plates (TP plate), cyclic loading tests, combined non liner FE analyses, pseudo-dynamic tests and dynamic FE analyses are carried out, in order to investigate its seismic performance. As results of cyclic loading tests and combined non liner FE analyses, it is shown that steel pier with TP plate have good seixsmic performances, and the taper ratio and the slenderness parameter are the larger, seismic performances are the better. And as results of pseudo-dynamic tests and dynamic FE analysis considering the real seismic acceleration, it is found that the response displacement of steel pier with TP plate is smaller than the one of ordinary steel pier.
