The purpose of this paper is to investigate the nonlinear behavior of a building structures with shear walls to horizontal loads such as seismic loads. A recent survey of earthquake damage cases shows that damage to shear walls is unexpected even in countries where relatively seismic design is strictly implemented. So far, many studies on nonlinear analysis modeling of shear walls have been conducted. However, the validity of analytical modeling with general properties applicable to seismic performance evaluation of actual building structures is insufficient. In this paper, nonlinear behavior of a shear wall with a T-shaped cross section, which is widely used in the cores of a three-dimensional building structure, is investigated under the positive and negative directional loading conditions. In this study, the nonlinear behavior of a shear wall modeled by fiber slices and shear spring elements, which are easy to apply in practice, is compared with experimental results and analytical results by applying a macroscopic modeling procedures. The conclusion of this paper is as follows. In the case of the load was applied in the positive direction, the test result underestimates the initial stiffness rather than the analytical result, and the yield strength is overestimated. In addition, the initial stiffness and the yield displacement at the negative direction load are in agreement with the experimental results, but the yield strength is underestimated compared with experimental results.
