In ultimate strength design, predicting accurately the deformation of a reinforced concrete column, up to the elasto-plastic stage, is very important. With this in mind, this study was carried out to clarify the deformation characteristics of reinforced concrete columns under high and/or fluctuating axial force. Reversed cyclic horizontal loading tests of six 4/13 scale high strength reinforced concrete column specimens under different axial loading conditions were conducted. The applied loads were based on the forces of the second floor columns calculated by the elasto-plastic seismic analyses of a 30-story reinforced concrete building. The test results made the assessment of the columns' strength and seismic performance feasible. A comprehensive investigation of the deformation characteristics was conducted by evaluating the flexural, shear, and other deformation components. The behaviors of the columns were observed to be significantly affected by the manner of application of the loads.
