Analysis on Seismic Performance of Steel Reinforced High Strength Concrete Columns

In the thesis, simulated analysis of eight steel reinforced high strength concrete column under the low reversed cyclic horizontal load were performed by using the nonlinear finite element software of ABAQUS.The hysteresis behavior, skeleton curve, displacement ductility energy-dissipating capacity of the steel reinforced concrete column under the combined action of the bending, pressing, and shearing were discussed in this thesis.And it also analyzed factors that affect the bearing capacity and ductility of the steel reinforced column, such as axial compression ratio, stirrup ratio, steel ratio.Results indicate that the displacement ductility factor between 2.43 and 3.95; The stirrup ratio have a greater impact on the seismic performance of steel reinforced high strength concrete columns.With the increment of volume-stirrup ratio and steel ratio, the ductility factor increases; As The axial compression ratio increased, bearing capacity increased correspondingly; When steel reinforced concrete column are under higher axial pressure, stirrup ratio has more significant effect on the bearing capacity of structure.
