Wood-steel hybrid vibration-damping braces suitable for medium to large-scale wooden structures, featuring a high-strength type equivalent to a wall multiplier of 17 times and a compact strut type, allowing for the minimization of columns and beams.
The "C-Wood Buckling-Restrained Brace System" is a wood-steel hybrid damping brace that sandwiches high-strength, high-toughness low-yield-point steel between wooden materials. It is designed to absorb vibrations while withstanding earthquakes, making it suitable for new seismic walls, damping systems, and seismic reinforcement of existing buildings. Due to its high strength compared to residential damping braces, it is well-suited for medium to large-scale urban wooden structures and public wooden buildings. **Features** - **High Strength**: The brace bears the seismic forces, allowing for the minimization of columns and beams or the reduction of wall surfaces, thus creating an open space. - **High Toughness**: It flexibly follows large vibrations. The low-yield-point steel undergoes plastic deformation first, resulting in a ductile framework. - **Excellent Damping Effect**: Strong against repeated earthquakes, it offers stable performance. It forms a spindle-shaped loop, demonstrating stable energy absorption capabilities. **Installation Types** - **Shear Wall Type**: High-strength wall equivalent to a wall multiplier of 17 times. - **Brace Type**: Compact shape primarily installed in moment-resisting frames. *For more details, please refer to the PDF document or feel free to contact us.*

basic information
**[Damper Configuration]** A buckling-restrained brace sandwiched between low-yield-point steel and wooden materials. The low-yield-point steel serves as the core material, constrained by the buckling-restraining material, allowing for stable and repeated plastic deformation. Since wooden materials are used for the buckling-restraining component, it is lightweight and economical. **[Installation Benefits]** Reduction in the number of shear walls (shear wall type) - Compared to conventional shear walls, the wall ratio is higher, allowing for fewer installations. Minimization of column and beam members (braced type) - By having the brace bear the horizontal forces, the cross-section of the columns and beams can be reduced. **[Vibration Control Effect]** Improved resilience with high vibration control effect - By installing braces with high hysteresis performance, building damage can be minimized, and vibrations can be suppressed early. **[Performance]** Both shear wall type and braced type have been confirmed to have stable hysteresis performance up to a shear deformation angle of 1/30 rad through full-scale structural testing. There was no decrease in stiffness or strength during repeated loading at the same displacement. *For more details, please refer to the PDF materials or feel free to contact us.*
