Behavior of hysteretic models including stiffness and strength degradation
초록
영어
Seismic performance evaluation of structure requires an estimation of the structural performance in terms of displacement demand imposed by earthquakes on the structure. Most structures are expected to deform beyond the limit of linearly elastic behavior when subjected to strong ground motion. In the context of earthquake engineering, nonlinear response history analysis is an important tool to predict with reasonable accuracy the building response for varying levels of ground motion intensity.
We can obtain nonlinear response though three hysteretic parameters such as strength degradation, stiffness degradation and pinching behavior respectively. In this study, it is to compare behaviors of hysteretic models through three hysteretic characteristics such as strength degradation, stiffness degradation, pinching behavior and to suggest more reliable hysteretic model for nonlinear analysis of structure.
