Japanese Patent JP7175694

B2

To provide a buckling constraint brace that is preferable to build in a frame of wooden building and be used and that can eliminate the breakdown by acting additional flexural moment to a wooden constraint material when the frame being largely deformed in large earthquake.SOLUTION: A buckling constraint brace 100 is provided with a steel core material 10 and a wooden constraint material 20 formed by a pair of wooden constraint plates 21 and a pair of wooden side plates 22. In the buckling constraint brace 100, reinforcement ribs 14 are attached at a wide width face of the end of longitudinal direction of the core material 10 to exhibit a cross-shaped cross section, slits 24 not interfering the reinforcement rib 14 are provided at the position corresponding to the reinforcement rib 14 within the wooden constraint material 20, and the core material 10 has a narrow width part 13 at the center side of longitudinal direction, has wide width parts 12 at the end sides of longitudinal direction and has clearances G1 between side faces of the wide width parts 12 of the core material 10 and the side plates 22.SELECTED DRAWING: Figure 3
