Paper Title:
Research on Hysteretic Model of SRHSHPC Frame Joints Considering Accumulative Damage
  Abstract

To reflect the effects of accumulative damage of steel reinforced high strength and high performance concrete (SRHSHPC) frame joints on its mechanical properties such as strength and stiffness degradation under reversed load, a damage index (D) is introduced into hysteretic model of SRHSHPC frame joints. Then a trilinear load-displacement hysteretic model of SRHSHPC frame joints considering accumulative damage is proposed, which can reveal strength and stiffness degradation of SRHSHPC frame joints. Five 1:4 reduced-scale models of SRHSHPC frame joints were constructed and subjected to low cyclic reversed loading to gain the value of those parameters in the D. The calculated results tally with the experimental results well, and it is showed that the proposed hysteretic model considering accumulative damage has a considerable precision.
