| Research Abstract |
In this study, the characteristics of wall-frame coupling structures considering uplift behavior at the footing are performed in biased lay out of the multi-story shear wall. The vibration experiment of shear wall considering uplift behavior at the footing are carried out. In oder to evaluate the significant effect for practical aseismic desigh, elasto-plastic analyzes for wall-frame coupling structures considering uplift or rocking deflections of the foundation of multi-story shear wall are made, and the modal analyzes of these structures are also applied.
The results obtained in this study are summarized as followings.
1.For vibration experiments of shear wall considering uplift behavior at the footing, it can be represented non-linear behavior of uplift deflection, and made analytical model for the uplift behavior.
2.For elasto-plastic analyzes for wall-frame coupling structures considering uplift or rocking deflections of the foundation of multi-story shear wall, it is examined the ultimate capacity of structures, the eccentricity on each floors, and the displacement of the torsion direction and the translation direction.
3.The torsional modes and the translational modes are obviously influenced by plan position or quantity of shear wall for wall-frame coupling structures. The frequencies and modes are especially depended on uplift or rocking deflections of the foundation of multi-story shear wall.
