Predicting seismic response to earthquake load which can happen during the span of the building and evaluating seismic performance are very critical research tasks in the context of earthquake engineering with respect to performance-based seismic design. The main objective of performance-assessment is to evaluate the behavior of a system at different seismic hazard levels. To predict structure response to earthquake load which can arise, it is necessary to understand nonlinear behaviors characteristics. Ideally, the nonlinear response history analysis should faithfully simulate all significant modes of deformation and deterioration in the structure from the onset of damage up to collapse. We can obtain nonlinear response through three hysteretic parameters such as strength degradation, stiffness degradation and pinching behavior respectively. In this study, it is to compare inelastic behaviors of reinforced concrete upper wall-lower frame structures and to suggest more reliable hysteretic models with simple bilinear model for nonlinear analysis of structure. From a limited sensitivity study, it is founded that strength degradation and pinching behavior have more effect rather than stiffness degradation on the top story response.
