Seismic and vibration control member for civil engineering and bridges: "Unbonded Brace"
Contributing to shorter construction periods and lower costs! Vibration control dampers that protect bridge structures in earthquake-prone Japan!
The "Unbonded Brace" is a hysteretic damper of the axial yielding type that can economically improve seismic performance by installing it as a damping material in structures such as brace-supported ramen bridges, applicable to both new and existing bridges. To efficiently absorb seismic energy, the seismic forces acting on various components are significantly reduced. This leads to a decrease in the amount of steel and reinforcement materials used, thereby enhancing cost-effectiveness. Furthermore, when used for seismic reinforcement of existing bridges, the number of sections requiring cross-sectional reinforcement is reduced, allowing for a shorter construction period compared to conventional seismic reinforcement work. 【Features】 ■ Economically improves seismic performance ■ Significantly reduces seismic response of each component ■ Enables shortening of construction period ■ Enhances maintenance management ■ Registered with NETIS [NETIS Registration Number: KK-100051-A] For more details, please refer to the catalog or feel free to contact us.

We were established in 1974 as the engineering division of Nippon Steel, and became an independent company in July 2006. What is required of us is the ability to think beyond conventional levels and solve problems related to global environmental conservation, effective utilization of resources and energy, safe and efficient land formation, biodiversity issues, and more. We do not remain merely as a hard supplier; through comprehensive engineering technology, we propose total solutions for problem-solving and have provided new value to our customers, paving the way in the market. This is our fundamental stance, which will not change now or in the future, and it is our joy.
