The lateral resistance of exterior RC columns subjected to both high varying axial force and lateral cyclic force with large amplitude decreases rapidly due to P-δ effect. In this paper, the seismic performance of multi-span multi-story RC frame with those columns were investigated through the tests using the mechanical models of the lower part of frames for high-rise RC buildings. Based on the experimental and analytical works, the following conclusions can be made. 1) Lateral restoring force characteristics of overall frames are of overall yielding types to the final stage. 2) Lateral envelope curves of restoring force characteristics and hinge mechanisum could be evaluated efficiently by the analytical method. 3) Re-distributions of shear force among columns in the multi-span frames were obtained in detail.
