Development of Simplified Hysteresis Model with Strain Hardening and
Pinching Effects
Abstract
Other than most of the existing sophisticated complex hysteresis models,
this study provides a simplified degraded and deteriorated hysteresis
model which can capture the cycle by cycle progressive damage with
greater accuracy due to inelastic reversal loading. The attention to the
proposed developed hysteresis model is given to capture the overall
behavior of the structure. The effect of post-yielding stiffness and
pinching resulting from high shear loads and slippage of longitudinal
reinforcement in Reinforced Concrete(R/C) members are considered and
incorporated in the proposed developed hysteresis model. Based on the
superimposition of curves and a comparison of hysteretic energy
dissipation between the simplified developed hysteresis model and the
previous model, minor deviations in the prediction of the inelastic
cyclic behavior of R/C structural members are observed.
