In order to research feasibility of high strength concrete applied to the main factory building frame and framed bent structure of large-scale firepower plant, based on the experimental research of 6 reinforced high strength frame slender columns under frequency cyclic loading, the failure shape and hysteretic characteristics were discussed. The main results show the surface concrete shedding of columns with high axial compression ratio and low hoop rate of the column drop more serious and those of columns with low axial compression ratio and high hoop rate drop slightly; with the decrease of axial compression ratio and stirrup ratio increases, the column hysteretic curve become increasingly full; the cumulative hysteretic energy become more and more big; the absorbed earthquake energy increases; the ductility also increases accordingly; whether high or low strength concrete frame column, with the axial compression ratio increases, the ductility decreases; the ductility of ordinary concrete columns is basically linear relation; the ductility of high strength concrete frame columns decreases nonlinearly with axial compression ratio increases.
