Generally, an exposed column base consists of anchor bolts and an elastic thick base plate. Restoring force characteristics of the column base are observed to be slip-type due to a gap between a nut of the anchor bolt and the base plate, caused by the plastic elongation of the anchor bolt. The cyclic characteristics for the column base with many lanes of anchor bolts are so complicated that only the models for the column bases with one or two lanes of anchor bolts have already been proposed. In this paper, the unified formulation for the models of cyclic characteristics for the column bases are proposed and are compared with experimental results. The following conclusions are drawn. 1) The restoring force characteristics of conventional column bases can be shown as slip-type models. 2) The models for the column bases with the anchor bolts on the axis of centroid of column are complicated and are shown discretely slip-type. 3) The slip-type models of cyclic characteristics for the column bases are in good agreement with the experimental results.
