In order to achieve the miniaturization of laminated rubber bearings, even increase the sealing rubber, compared with highway bridge bearings can achieve lower costs. Using the rubber bearing itself changed into rubber bearings or pins inserted lead rubber bearings can achieve damping requirements, because mixed in advance of the bearing structure, highway bridge bearings do not need support while using vertical and horizontal Both types of bearings supporting the bridge bearing gyzf4, providing construction type and shorten the construction period is entirely possible. Since the multi-layered structure can be made, significantly improved vertical stiffness, the traffic generated by the vibration can be reduced. Compare highway bridge bearings and general bearing, hybrid bearing with ordinary laminated rubber bearings in the functional differences generally have the following conditions; highway bridge bearings gjz bridge bearings, the ordinary laminated rubber bearings can be applied to the main vertical load support function, fit and function rotational displacement of bridge bearings dpz, highway bridge bearing horizontal displacement applicable function, to ensure that the function held to overcome limitations due to the layered structure resulting constraints, proper implementation and bearing natural period guarantee the stability of the case itself will have problems. Combined highway bridge bearing damping capacity and bridge damping damping demand for bridge design drawn highway bridge bearings used in the selection system class diagram, this is only for the principles and methods of highway bridge highway bridge bearings standardization proposed direction but it is a problem to be further studied. Should and should pay attention to the problem of lead rubber bearing. Highway bridge bearings with lead-free rubber bearing compared to driving to the initial elastic stiffness. It is precisely because the initial elastic stiffness of large highway bridge support, so it can do is higher than highway bridge bearing pin lead-free number, and in the earthquake LRB stiffness decreased rapidly, to a certain natural cycle extension bridges extent, at the time of the earthquake LRB can play bridge bearing performance can be even good energy absorption system and the relationship between the phase change between the top of the pier, changing earthquake process The maximum energy value of the structure, which can reduce the maximum value of the impact structure.
