Abstract
Experimental works for steel bridge piers have been conducted in order to investigate their earthquake resistance. After the Hanshin-Awaji earthquake in 1995, not only static but also psudo-dynamic tests have been conducted to study the mechanical behavior of steel bridge piers. Those experimental results may be used to establish the design formulae. In this paper, new parameters are proposed to predict the ultimate strength of steel bridge piers. The validity of the parameters are confirmed by using the existing experimental results.
