Determining Hysteretic Parameter Model for RC Shear Wall

In seismic performance-based design, this is required to have comprehensive knowledge about the nonlinear behavior of components. In time history analysis which is the most power full tool for predicting the structural response, the hysteretic model of the plastic hinge is needed. Hysteretic models are defined with some parameters that show strength, stiffness, ductility, deterioration, degradations, and other characteristics such as reversal path. Hysteretic parameters can be adopted from different methods including experimental results, finite element analysis, and mechanical engineering relation. The main goal of this research is to determine and extracting the shear wall hysteretic parameter from the existing experimental test results. The hysteretic parameters have been extracted from 135 sample test data for the slender shear wall and 99 sample test data for the squat shear wall in this study. All experimental test data has been simulated in OpenSees software using the modified Ibarra-krawinkler models and their hysteretic parameters are extracted. Finally, some statistical analysis has been performed and the representative values of these statics are presented.
