Bridge Pier Damper Method

A new method to enhance the seismic performance of bridge piers using seismic dampers!

The "Pier Damper Method" is a technique that improves the seismic performance of bridge piers by installing a damping device between the pier and the footing to absorb seismic energy. By selecting the yielding axial force of the damper, the increase in the pier's load-bearing capacity can be controlled. Compared to conventional methods, this approach significantly enhances energy absorption capability, allowing for a reduction in the additional load from pier reinforcement and minimizing the need for foundation strengthening. The damping device used is the "Double Steel Pipe Damper for Bridges," which has a proven track record. 【Features】 ■ Excellent seismic reinforcement effect ■ The damping device maintains support capacity even after the load-bearing capacity of the pier has decreased, preventing collapse ■ A method for partially installing damping devices ■ Easy to construct even in narrow spaces ■ Damage inspection after an earthquake is straightforward, shortening the process for reinforcement and recovery work *For more details, please refer to the PDF document or feel free to contact us.
