REINFORCING STRUCTURE FOR COLUMN AND BEAM FRAME
To provide a reinforcing structure of a column and beam frame capable of avoiding buckling of right and left connecting braces even if a large axial force concentratedly acts on the right and left connecting braces by an earthquake and improving strength as a whole reinforcing structure.SOLUTION: A reinforcing structure of a column beam frame, wherein upper parts of left and right columns 1, 2 are joined to an upper beam 3 via a left and a right joint parts 5, 6, and a first and a second left braces 8, 10 joined to the left joint part 5 and the upper beam 3 constitute a left brace body 12 having a left end joint part 11; a first and a second right braces 14, 16 joined to the right joint part 6 and the upper beam 3 constitute a right brace body 18 having a right end joint part 17; a left connecting brace 19 connected over the left end joint part 11 and the lower end part of the left column 1, and a right connecting brace 21 connected over the right end joint part 17 and the lower end part of the right column 2 are each constituted of buckling stiffening braces.SELECTED DRAWING: Figure 1
【課題】たとえ地震によって左右の連結ブレースに大きな軸力が集中的に作用しても、左右の連結ブレースの座屈を回避することができ、補強構造全体としての強度向上も図り得る柱梁架構の補強構造の提供。【解決手段】左右柱１、２の上部が、左右接合部５、６を介して上部梁３に接合され、左接合部５と上部梁３に接合の第１と第２左ブレース８、１０が左端部接合部１１を有する左ブレース体１２を、右接合部６と上部梁３に接合の第１と第２右ブレース１４、１６が右端部接合部１７を有する右ブレース体１８を構成する補強構造で、左端部接合部１１と左柱１の下端部に亘って接合の左連結ブレース１９と、右端部接合部１７と右柱２の下端部に亘って接合の右連結ブレース２１とが、それぞれ座屈補剛ブレースで構成される。【選択図】図１
