| Outline of Final Research Achievements |
Shear walls deform not only in in-plane direction but also in out-of-plane direction by earthquake ground motions. Little experimental data of structural wall failing in shear are available on the influence of out-of-plane deformation on in-plane seismic resistance. The objective of this study is to investigate the influence of out-of-plane deformation on in-plane shear resistance of wall failing in shear. From experimental study on three 1/3-scale reinforced concrete shear wall specimens, it is clarified that the maximum lateral loads of the specimens subjected to bi-directional loading were approximately 8-18% less than that of the specimen subjected to uni-directional loading. Based on the experimental results, an estimation method for shear capacity of shear walls under bi-directional loading was proposed. In addition, three-dimensional finite element model was constructed for simulating experimental behavior of the shear wall specimens.
