Notes:
Based on experimental investigation under low cyclic reversed loading, the seismicbehaviors and seismic damage model for steel reinforced high strength and high performanceconcrete (SRHSHPC) composite frame columns are studied. Several existing seismic damage modelsare firstly presented and their characteristics are comparatively analyzed. From the test results of lowcyclic reversed loading, the variation history of cumulative dissipated hysteretic energy of theSRHSHPC composite frame columns under different loading cycle levels is figured out, and theinfluence of axial compression ratio, shear span ratio, stirrup ratio and concrete strength on thecumulative dissipated hysteretic energy is also discussed. The damage index of the SRHSHPCcomposite frame columns is compared according to the existing seismic damage models, and theseismic damage model adapted for the SRHSHPC composite frame columns is established.According to the variation history of the damage index under different loading cycle levels, the rule ofdamage development for the SRHSHPC composite frame columns is proposed. The influence of axialcompression ratio, shear span ratio, stirrup ratio and concrete strength on the damage development isalso discussed. The results indicate that the seismic behaviors of the SRHSHPC composite framecolumn are outstanding, and the seismic damage model could give a quantitative description fordamaging process of the samples, which is reference for establishing more rational damage criteria forthe SRHSHPC earthquake-resistant composite structure
