BUCKLING BRACE
PROBLEM TO BE SOLVED: To provide a buckling brace capable of avoiding breakage of a member due to stress concentration on the member in bending deformation while securing large earthquake energy consuming capability not only by deforming the member axially, but also by bending and deforming the member.SOLUTION: There is provided a buckling brace 1 formed by connecting a first long-sized body 2 made of low yield point steel and a second long-sized body 3 made of high-strength steel to each other in a longer direction. In a cross section of the buckling brace 1, the first long-sized body 2 and the second long-sized body 3 are arranged asymmetrically about a predetermined axis, and the bucking brace 1 is configured to bend in a direction crossing the axis in the cross section and to the side where the second long-sized body 3 is arranged when compressive force or tensile force in a long-axis direction acts on the buckling brace 1.
【課題】軸方向変形だけでなく曲げ変形を部材に与えることでより大きな地震エネルギー消費能力を確保しつつ、当該曲げ変形に際し部材に応力集中が生じて当該部材が破損するのを回避することができる座屈ブレースを提供する。【解決手段】低降伏点鋼からなる第１長尺体２と高強度鋼からなる第２長尺体３とが長手方向に沿って互いに連結された座屈ブレース１。座屈ブレース１の横断面において、第１長尺体２と第２長尺体３とが所定の軸に関して非対称に配置されており、座屈ブレース１に長手軸方向の圧縮力又は引張力が作用したときに、横断面内において軸に直交する方向であって第２長尺体３が配置された側に座屈ブレース１が曲がるように構成されている。【選択図】図１
