モードは靭性に欠けるものとなる。 Since the conventional multi-story continuous span shear wall has a large cross section, it is difficult to bend and yield the legs. Therefore, the shear wall causes uplift at the tension side leg, and then shear failure occurs at a certain layer. Such a failure mode results in a lack of toughness.

耐震壁に係るものである。(Means for Solving the Problems) The present invention was proposed in order to solve the above problems, and the central structural surface part of the multi-story continuous span wall has upper and lower wall heads and legs. A wall with low shear strength is installed that is connected to the beam and floor so as to cause shear shear deformation, and on both sides of the structure, there is a curved wall of reinforced concrete structure that is integrated with the outer columns and beams. This relates to a multi-story continuous span shear wall characterized by a structure in which a body is arranged.

水平変形を小さくする。(Function) and (Effects of the Invention) As described above, the shear wall according to the present invention has a wall with low shear strength disposed in the central structural face part of the multi-story continuous span wall, and a wall body with low shear strength is provided on both side structural faces. Since the walls are curved, the entire shear wall behaves as a multi-layered wall with high strength and rigidity in the event of a small to medium earthquake, reducing horizontal deformation of the entire building.

形モードに移行する。 A conventional multi-story continuous span wall is a staircase where the shear force reaches QW 0 , and shear failure occurs at a certain level, but in the shear wall of the Shiki example, the shear force at the central structure reaches a certain value QW 1 . When this point is reached, the low shear strength wall structure undergoes sequential shear displacement deformation, and finally shifts to the deformation mode shown in FIG.
