Abstract

The prediction of nonlinear behavior of shear walls under lateral loads requires simple and precise analytical models representing the nonlinear behavior of the shear walls as well as the experimental results. In recent decades, various analytical models have been proposed by researchers to predict the nonlinear behavior of reinforced concrete shear walls in order to consider the most important behavioral properties of the wall. The model used for analysis and design of the wall should be simple and accurate enough to predict the hysterical behavior. Using the method of Fiber section elements can be considered as one of the most accurate methods in wall modeling. But due to the complexity of the modeling and high duration of the analysis, the use of other methods is suggested. Considering the recent progress in modeling nonlinear behavior of materials to provide more accurate behavior against cyclic and seismic loads, these material models can be directly used in modeling of structural systems. In this study, in addition to using the Fiber section model, a method based on Axial elements is also used. It is implemented by the concept of equivalent spring’ s behavior and using the advanced material models in the platform of OpenSees. The results show that the use of this simplified model compared to the fiber method, in addition to reducing the computational cost in both aspects of the duration of modeling and analysis, also satisfies the desired accuracy.
