EARTHQUAKE STRENGTHENING STRUCTURE
To enhance shear capacity without increasing shear rigidity of an existing concrete wall.SOLUTION: An earthquake strengthening structure 10 includes: an existing frame 20 that has a pair of existing columns 22, and upside and downside existing beams 80U and 80L erected between the pair of existing columns 22; an existing concrete wall 30 that is provided within the existing frame 20 and joined to the upside and downside existing beams 80U and 80L; and a beam-like additional reinforcement part 82 that is provided for the existing concrete wall 30 and that decreases a shear-span ratio of the existing concrete wall 30 by forming a beam laid across the pair of existing columns 22 together with an upper part 30U of the existing concrete wall 30.SELECTED DRAWING: Figure 2
【課題】本発明は、既存コンクリート壁のせん断剛性を高めずに、せん断耐力を高めることを目的とする。【解決手段】耐震補強構造１０は、一対の既存柱２２と、一対の既存柱２２に架設された上側既存梁８０Ｕ及び下側既存梁８０Ｌと、を有する既存架構２０と、既存架構２０の架構内に設けられ、上側既存梁８０Ｕ及び下側既存梁８０Ｌに接合された既存コンクリート壁３０と、既存コンクリート壁３０に設けられ、既存コンクリート壁３０の上部３０Ｕと共に一対の既存柱２２に亘る梁を形成し、既存コンクリート壁３０のシアスパン比を下げる梁状増打ち補強部８２と、を備える。【選択図】図２
