The seismic performance of the grid structure is very outstanding. The editor of Jiangsu Huahai Steel Structure will introduce the seismic characteristics of the grid support in detail:

The seismic support of the grid structure adopts elastic damping elements. When the horizontal force reaches a certain level, the damping elements begin to deform. When an earthquake comes, it can withstand huge seismic energy. This can ensure reasonable relative displacement of the upper and lower structures of the bridge, reduce the magnification factor of the seismic force, and maintain the unity of the structure.

The main technical performance of the grid seismic support:

1. Can bear vertical load;

2. It has the performance of resisting vertical tension and horizontal force to ensure that the beam will not fall during a horizontal earthquake;

3. It can meet the requirements of radial and circumferential displacement and the requirements of rotation angle in any direction;

4. The bearing has good shock absorption performance, and the overall performance is also very good; 5. The bearing transmits the force through the spherical surface, and there is no force necking phenomenon, and the reaction force acting on the upper and lower structures is relatively uniform.
