1. Vertical bearing capacity range: 3500KN -50000KN.
When the vertical bearing capacity is more than 50000KN, it can be designed separately.
2. The design angle of the bearing:
● Longitudinal direction: 0.02rad.
● Transverse direction: 0.01rad.
3. Design horizontal force (main force)
The design horizontal force of the fixed bearing, the longitudinal movable bearing in the transverse bridge direction, and the transverse movable bearing along the bridge direction is 15%, 20% of the vertical design bearing capacity of the bearings:
● 15%-In the area with acceleration of peak ground motion is Ag ≤ 0.1g
● 20%-In the area with acceleration of peak ground motion is 0.1g<Ag≤0.2g
The design horizontal force of the two way movable bearing in each direction, the longitudinal movable bearing along the bridge direction and the horizontal movable bearing in the transverse direction is 5% of the vertical design bearing capacity of the bearing.
When the peak acceleration is greater than 0.2g, it can be designed separately
4.The design displacement range of this series of bearings is as follows: ±50mm, ±100mm,±150mm,±200mm,±250mm.
When the required displacement is greater than the above value, it can be designed separately.
5. Design friction coefficient of bearing: Design friction coefficient of movable bearing with silicone grease lubrication:
● Normal temperature: μ≤0.03
● Cold resistant type μ≤0.05.
6. Temperature Range: - 50℃～ 60℃
7. When the bearing is used on the ramp, the beam bottom concrete is used to adjust the slope, and the bearing roof does not preset the slope.
