EXISTING BUILDING EXTENSION METHOD AND SEISMIC RETROFITTING METHOD
PROBLEM TO BE SOLVED: To construct an upper extension section on an existing building without increasing seismic force acting thereon and to reduce a seismic load on the existing building by utilizing a mass of the upper extension section.SOLUTION: A vertical load (Wb) of an existing building (B) is reduced by removing an uppermost floor thereof or a structure (2) of a plurality of floors at an uppermost section thereof. Then, an upper structure body (A), which has a plurality of floors with a load (Wa) not more than the reduced vertical load (Wx) by removal, is constructed on the uppermost section of the existing building. A total floor area (Sa) of the upper structure body is larger than the floor area (Sx) of the removed structure. A seismic isolation device (3) and a vibration control device (4) are installed in a space between a top section (10) of the existing building and a foundation section (11) of the upper structure body. The vertical load of the upper structure body is transferred to and supported by the existing building through the seismic isolation device.SELECTED DRAWING: Figure 1
【課題】既存建築物に作用する地震力を増大することなく、上層増築部分を増築するとともに、上層増築部分の質量を利用して既存建築物の地震時の負荷を軽減する。【解決手段】既存建築物(B)の最上層階、或いは、既存建築物の最上層部の複数階の構造体(2)が撤去され、既存建築物の鉛直荷重(Wb)が軽減する。撤去により軽減した鉛直荷重(Wx)以下の荷重(Wa)を有する複数階層の上層構造体(A)が、既存建築物の最上部に増築される。上層構造体の床面積(Sa)は、撤去された構造体の床面積(Sx)よりも大きい。既存建築物の頂部(10)と上層構造体の基部(11)との間に免震装置(3)及び制振装置(4)が介装される。上層構造体の鉛直荷重は、免震装置を介して既存建築物に伝達し、既存建築物によって支持される。【選択図】図１
