Experiments of twelve specimens were reported in the previous papers. The papers were titled "STUDY ON THE RESTORING FORCE CHARACTERISTICS OF REINFORCED CONCRETE COLUMNS TO BI-DIRECTIONAL DISPLACEMENTS" and published in No.286 and No.296 of the Transactions. A method to evaluate the experimental results and a restoring force model were presented also in them. Two specimens newly tested are added in this paper. The evaluation method and the restoring force model in the previous papers are modified. A method to evaluate tne restoring force characteristics of a column subjected to bi-directional displacement history is newly proposed. Experimental results of fourteen specimens, in which N/BD<F_c/10 and Q_<AS>>2M_y/h, are evaluated according to tne proposed method. All the specimens tested are evaluated to have good aseismic perfor mance judging from the fact that the hysteretic energy absorption capacity and the deformability are both large. A practical restoring force model is newly formulated. It follows the experimental results quite well.
