Ball bearing ball bearing damping amount is too large, the factors affecting the quality and great, so you can not put a lot more work ahead of yellow rubber bearings for posterity, although the design when considering a replacement measure, but the replacement plate system so much that called the cradle easier said than done, so the one-way slip damping spherical bearings, ball bearing bridge design should put a good man and expensive first hurdle. In revising the bearing industry norms and standards of bridges and culverts, the project team for disposal information and international standards, foreign as well as domestic standards for all willing to achieve the relevant technical levels were fully reflected, revised standards, and norms solicit Bright-way activities designed damping system spherical bearings, construction, production, management and the opinions of experts, also sought the views of system-level detection, municipal, quality supervision, the manufacturer's advice. A type of ball bearing type belong rubber bearing, in earthquake-prone areas must consider earthquake building bridges so that when the local earthquake can make a bridge to maintain its function, so as to ensure the smooth progress of relief and post-earthquake work. Reduce the losses caused by the earthquake, the ball bearing damping design, rubbing the bridge structure can support up and ball bearings to make structural vibration in the long period of the same time, by LRB dissipative vibration energy, thereby reducing damage to the bridge structure seismic crews. Rotational displacement of the upper structure for the deflection produced. Generates a corresponding bump in the free side of the laminated rubber bearing ball bearing to withstand external force shown in the following, at any point within the bearing, rubber bearings by design loads Effect reliable performance of laminated rubber bearings, ball seat has good elastic properties, can reduce the impact of dynamic load effects on the structure and piers of the bridge span, thus improving the overall force and bridge seismic performance. Height is low (such as for steel bearing on the general height of the small and medium span bridges for 90 ~ 180mm unidirectional damping movable spherical bearing ball bearing construction, while the corresponding laminated rubber bearing construction height of only 28 ~ 56mm), ease of construction, installation and replacement. Ball bearings than the usual seismic rubber bearing can reduce the level of power generated by the beam deflection, therefore, from travel and seismic point of view, I hope to be studied in the future as much as possible from multi-span continuous development direction.
