Vertical inclination of the beam should be adapted to be controlled when, in order to ensure not obvious bearing shear deformation. Highway bridge bearings along the short side of the general direction of the bridge should be placed, in order to facilitate the beam end rotation, according to the long side if need be placed along the bridge to that corner must be checking. Highway bridge bearings isotropic, without considering directional installation, just round the highway bridge bearing design to coincide with the position of the center in order to prevent the centrifugal force so that lateral movement of the beam to produce a two-way sliding hinge support generally can be set on the outside of the transverse beam stopper pier becomes limited. On the bridge of the installation, the use of a parallel skew quadrilateral same bevel rubber bearings, bearing at this time should be parallel to the short side of the bridge along the long side should be parallel to the centerline of the piers, along the bridge to the pier bevel angle between the centerline station should be consistent with the bearing of an acute angle, said the highway bridge bearings installed, but under normal circumstances, does not recommend the use of such bearings, bearing joints due to the use of force should be used not isotropic deformation The circular plate highway bridge support is appropriate. Highway bridge bearings and the Bay Bridge to the bridge of the use of laminated rubber bearing, should pier, station set up on both sides of the transverse radial limit stopper single seat, or on the lower end of the beam between the steel bearing plates and set up anti- shift stopper and other measures. Equivalent stiffness type highway bridge bearings main performance table table, when a major earthquake in the area of ??the equivalent stiffness of the lead pin bearing little impact, but then bearing great influence, so the first rubber damping rubber bearings can hinge bearing fixed bearing, mainly because it's sake, therefore, in the design and the actual use of lead rubber bearings should be noted that the following problems. If too large, not necessarily consume more energy, because then highway bridge bearing deformation may become less loyal to the part of the pier top bearing deformation, and reach a better shock absorption effect. Therefore, the practical application of damping bearings should be the appropriate choice. When the earthquake lead rubber bearings highway bridge has good damping effect, but when a small earthquake LRB almost no damping, highway bridge supports or is likely to magnify a certain extent, the seismic response seat while the former rubber rubber bearing bridge can often improve performance. Damping is conditional, different damping effects at different seismic waves, choose a better damping effect of the bearing under certain seismic waves, may not reach a better reduction in another seismic waves Different shock effects, it should be considered in practical application areas, conducted a detailed analysis of different bridge structures, select the appropriate damping bearings.
