E-shape steel damping bearing is a new model damper combining the characteristics of the common bearing and the elastic-plastic steel damper. E-shape Steel damping bearing combines the one-way common Pot rubber bearing with the elastic-plastic E-shape steel damping element. In the case without earthquake or only with a small seism, E-shape steel damping element does not work, serving as a fixed Pot rubber bearing; in the medium or large earthquake, the E-shape steel damping element will dissipate the seismic energy put into the bridge with the elastic-plastic deformation of the metal material to avoid or minimize the damage of the bridge, further saving the cost for the maintenance of bridge suffering from the seismic disaster. The bearing has the advantages of significant effect for energy dissipation and damping, simple structure, small-space for installation, easy maintenance and no influence from the environment. Therefore, it is widely accepted by various designers and construction companies.
Kunming Southeast Loop Line, Kunming Terminal, Hantaichuan Large Bridge at Inner Mongolia, Yellow River Large Bridge at Inner Mongolia
Kunming Terminal located in octave earthquake zone. In order to reduce the influence of seismic forces on bridge structure and improve the safety of the structure under seismic action, the simple beam adopted TJGZ - E-shape steel damping bearing.
Yellow River Large Bridge at Inner Mongolia
Yellow River Large Bridge at Inner Mongolia is located in the downstream of Danfuqiao of Tianjiage of Baotou, Inner Mongolia. Its main bridge is 12 across variable cross-section continuous box girder (60 + 10 x 100 + 60 meters) and the approach span is 50 meters cast-in-place continuous box girder. Yellow River Large Bridge at Inner Mongolia used E-shape steel damping bearing to reduce the difficulty of bridge design, reduce the project cost and extend the service life of bridge structure.
