Damage Analysis of the SRHSHPC Frame Columns under Low Cyclic Reversed Horizontal Loading

Abstract:

Based on tests under low cyclic reversed horizontal loading, damage behaviors of steel reinforced high strength and high performance concrete (SRHSHPC) frame columns are analyzed. The strength attenuation that considered as damage variable is figured out, and the influence of axial compression ratio, shear span ratio, stirrup ratio and concrete strength on the strength attenuation is discussed. The accumulative damage model, which can reveal the effect of cyclic loading and maximum deformation, is established for the SRHSHPC frame columns. The different phases of damage growth and their features for the SRHSHPC frame columns are analyzed, and the relation of damage and displacement is ascertained. Furthermore, the influence of axial compression ratio, shear span ratio, stirrup ratio and concrete strength on the damage development is also discussed. The results show that the damage model could give a rational description for damaging process of the SRHSHPC frame columns.
