1.lead rubber bearings | LRB rubber bearing,applied to building and bridge constructions,is a practical and cost-effictive choice for seismic isolation. It is composed of laminated elastomeric bearing pad, with lead in the center of bearing. This serises of bearing is suitable for 8 degrees and the earthquake intensity area of highway and municipal bridge. |
2.High damping rubber bearings | Its structure is the same as ordinary laminated rubber bearings,High Damping Rubber Bearing is improved through rubber formula,so that the rubber material damping is increased,so that the bearing's damping ratio can reach 15-18%.this series of bearing is suitable for 9 degrees earthquake intensity area of highway and municipal bridge. |
1,In addition to itself the isolation of mechanical performance meet the requirements of seismic design and use, lead isolation rubber bearing has better durability, resistance to low cycle fatigue properties and thermal air aging, ozone aging resistance, acid resistance, good water resistance are all its life up to 60-80, during the period of isolation mechanical properties will not change significantly, that is to say within 60 years does not affect the use, visible, and the buildings have the same life. |
2,With sufficient horizontal stiffness, ensure that the structure of the basic cycle extended to 1.5 ~ 3.0 seconds;The vertical ultimate bearing capacity, in addition with enough to stable supporting structures. |
3,With large enough reserves of horizontal deformation, to ensure that under the earthquake action on won't appear the phenomenon of instability. |
4,The influence of horizontal stiffness by vertical compression load is small. |
5,Design and construction is convenient. |
1,The lead core rubber bearing's building, can properly reduce the fortification level of the upper structure, can make the building layout more flexible, and can reduce some structural measures of the structure and size of some structures or reinforcement, save construction cost. |
2,Building on the premise of guarantee the aspect ratio can improve one to two layers, so that to improve the structure of the plot ratio, save the land for construction purposes. |
3,Can improve the level of a fortified, 7-15% lower cost. |
4,Ensure safe use of the building and the safety of life and property of the people, for the earthquake comes, the emergency rescue, command and stability is of great significance. |
