Conventionally, in-situ concrete or precast concrete wall structures that are generally employed are difficult to control strength and rigidity, and it is difficult to expect deformation ability while maintaining a predetermined strength. The required performance of the shear wall is to design the rigidity and strength appropriately. That is, the variable stiffness function having a high strength against seismic force and excellent deformation performance (toughness) with high proof stress is satisfied. Inventions aimed at achieving this object are disclosed, for example, in Patent Documents 1 and 2 below. However, the disclosed inventions of Patent Documents 1 and 2 cannot control the bending rigidity with respect to the out-of-plane force. Patent Document 3 discloses a corrugated plate-made disaster-shielding wall in which a deck plate (corrugated steel plate) is incorporated in the plane of a column beam frame or a column slab frame. The technical idea of the seismic wall that I focused on has not been heard yet.
Japanese Patent Publication No.62-31148 Japanese Patent No. 2944050 In order to achieve the above object, the present applicant also resists horizontal shearing force, but has low resistance to vertical axial force and bending in the out-of-plane direction, and design of rigidity and strength. A seismic wall with a high degree of freedom was developed and a patent application was filed separately (Japanese Patent Application No. 2004-224230 or Japanese Patent Application No. 2004-221368).

The corrugated steel sheet has a folded plate shape in longitudinal section, and the shape is formed, for example, in a rectangular wave shape to obtain mechanical characteristics. The cross-sectional shape of the corrugated steel sheet is not limited to this, and refers to, for example, the trapezoidal wave shape (FIG. 7A), the triangular wave shape (FIG. 7B), the circular arc shape (FIG. 7C) and the like illustrated in FIG.

Further, since the corrugated steel plate is a folded plate, the axial force perpendicular to the corrugated streak freely expands and contracts like an accordion, and the rigidity proof stress is much smaller. Also for bending in the corrugated plane, it expands and contracts freely like a similar accordion and allows compression and tension, so that rigidity and proof stress are small. On the other hand, the rigidity and proof stress against the out-of-plane force (bending and shearing) in the direction perpendicular to the corrugated folding line is sufficiently large because it is a folded plate, but the out-of-plane force (bending and shearing) in the direction parallel to the corrugating folding line. With respect to (shearing), since it is a folded plate, it exhibits a mechanical characteristic that resistance becomes small.
