【発明の属する技術分野】耐震性の弱い既存建築物に於
いて、既存の壁を用いて耐震性を向上させる壁の構造に
関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall structure for improving the earthquake resistance of an existing building having low earthquake resistance using existing walls.

耐震性の弱い既存建築物を耐震補強する場合、新たに柱
或いは壁等を増設する方法が採用されていた。2. Description of the Related Art
When existing buildings with weak earthquake resistance are reinforced by earthquake resistance, a method of newly adding columns or walls has been adopted.

い。[0003] Even if additional columns or walls are provided, if the columns or walls are themselves fragile, the number of columns or walls required to obtain the required seismic strength increases. Therefore, the weight of the building increases and the effective use space is limited, which is not preferable.

記垂れ壁と腰壁を接合する構造とする。Means for Solving the Problems A vertical slit is provided along the pillars at the left and right ends of the wall, which is the seismic element of the existing building, at the sides of the pillars. In addition, a horizontal slit is provided in the middle part of the wall, and the wall is an independent hanging wall and a waist wall, and the hanging wall and the waist wall are joined to each other by a vibration control device such as an elastic-plastic damper, a viscous damper, and a visco-elastic damper. Structure.

てもよい。Further, a slit may be provided separately from the beam and the wall on the upper floor or the beam and the wall on the lower floor, and the vibration damping device may be arranged in the slit.

ギを吸収する。[0007] By making the existing wall an independent hanging wall and a lumbar wall, the deformation of the entire building due to the earthquake becomes an independent hanging wall and a lumbar wall, respectively. That is, relative deformation occurs between the two, and the vibration damping device absorbs vibration energy against the relative deformation.
