This study deals with the demand predictions of partially concrete-filled steel bridge piers. For this purpose, two types of dynamic analysis procedures for such structures are presented. First, a SDOF model analysis procedure based on the force-displacement hysteric model derived by means of the pushover analysis is established. Second, a fiber model analysis procedure based on the cyclic stress-strain relations of concrete and steel is developed. The analyses are carried out for specimens tested by Pseudo-dynamic testing procedure, and comparisons are made between results obtained through the analytical methods and tests. The effects of concrete material behavior on predictions were further examined by conducting additional analyses using a simple cyclic stress-strain model of concrete. It is found that the maximum displacement demands computed using the fiber model analysis procedure exhibits good agreement with test results. In addition, results obtained from the SDOF model analysis with the tri-linear model seem to be better than that of the bi-linear model.
