Seismic measures for new and existing bridges: damper braces

A mechanism that absorbs energy and reduces cross-sectional forces! Applicable to both new bridges and seismic reinforcement of existing bridges.

The "Dampers Brace" is a steel damper developed with the aim of absorbing seismic energy, featuring an axial yield type design. The core material is restrained by components that prevent buckling during axial compression, allowing for stable repeated plastic deformation in both tension and compression directions, which results in high hysteretic damping performance. This hysteretic damping absorbs seismic energy. It is possible to significantly reduce the forces acting on the main components of bridges. By adopting this product, the necessary seismic performance can be achieved efficiently and economically compared to conventional seismic reinforcement designs. 【Features】 - The reduction in seismic countermeasure weight can significantly lower manufacturing costs and vertical reactions, making it economical. - It can reduce the horizontal seismic reactions from the superstructure to the substructure. - It allows for a smaller scale of substructures, which is economical. - It is applicable to both new bridges and seismic reinforcement of existing bridges. *For more details, please refer to the PDF materials or feel free to contact us.
