Achieving reduced construction costs and lightweight, compact design! Energy-absorbing bridge collapse prevention device.
The "Tai-Bridge" is a system that excels in the cushioning effect required for bridge anti-fall devices and has a structure capable of absorbing the energy generated during a large-scale earthquake. It has superior shock absorption performance compared to conventional rubber cushioning devices, making additional cushioning devices unnecessary. Additionally, it allows for the verification of cable action loads during an earthquake, and only the control pipe section can be replaced. Our company also offers many other products related to bridge structure projects. 【Features】 ■ Demonstrates sufficient energy absorption performance even during large-scale earthquakes ■ No additional cushioning devices are needed due to excellent shock absorption performance ■ Capable of integrating horizontal force distribution and anti-fall functions within a single structure ■ Makes horizontal force distribution structures in the bridge axis direction unnecessary ■ Easy maintenance and management of the support sections ■ Achieves structural simplification and high economic efficiency *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Function】 ■Always - Movement and rotation of the bearings due to temperature changes and live loads are accommodated by the expansion and contraction of the springs. ■Small-scale earthquakes - Bearings resist seismic forces. ■During large-scale earthquakes - Control pipes resist seismic forces (working in conjunction with bearings to resist inertial forces). ■Seismic forces or displacements exceeding expectations - Preventive measures against bridge collapse (supplementing the girder overhang length). *For more details, please refer to the PDF document or feel free to contact us.

Company information
In 1967, SE Corporation introduced the SEEE method domestically from the French company S.E.E.E. (now ingérop) and was established. Forty years have passed since our founding, and along with the times, not only have our technologies and methods changed rapidly and significantly, but the business environment surrounding us has also transformed. However, our fundamental stance of "aiming for a rich social environment and harmony with nature while continuously providing new value" remains our unwavering foundation. Moving forward, we will actively contribute to society by providing world-class technology and systems to revitalize the development of social infrastructure, which is the foundation for protecting people's lives and property, and we will continue to challenge ourselves as a united group aiming to become a "global engineering manufacturer."
