Such modeling can be accomplished by using microscopic or macroscopic models. Therefore due to various complexities involved in the former models, the later models are more effective due to relatively simple implementation and reasonably accurate in predicting the response of RC walls. This study discusses the tension axial stiffness ratio proposed in an existing procedure (Kabeyasawa macro-model for shear walls), which is widely used by researchers and design practicing engineers for modeling reinforced concrete walls. The feasibility of a different application of the original model was checked through pushover analyses and test data. Test data of wall specimens with boundary columns and wall specimens with rectangular sections were used. The examination procedure was based on two parameters: the variation of the number of panels constituting a given wall and the simultaneous variation of the tension axial stiffness ratio of both panels and columns along the wall-height. From the results of several simulations on different modeling and their matching to test results, suitable varying values of the tension stiffness ratio were selected according to the number of panels. They are presented and suggested for a better assessment of structural wall seismic response.
