Abstract
A fixed point bridge bearing assembly having a generally U-shaped channel having a base and end walls extending upwardly from said base. A load plate is supported within said channel. The load plate has spaced parallel end edges confronting the end walls. The load plate extends vertically above the end walls. Each pair of end walls and end edges defines an elongate gap therebetween. An elastomeric, supporting bearing body, which preferably embeds at least one shim, is bonded to and positioned between the load plate and the base. The bearing body supports the load plate within the channel. An elastomeric bearing body is positioned in each gap and is bonded to the end wall and end edge. Those bodies compressively resist movement of the load plate toward the end walls, while permitting rotation of the load plate and an associated beam relative to the channel. When fixed in a bridge construction, the bearing assembly end walls are transversely oriented relative to the length of the load carrying member, the channel is secured to a bridge support and the load plate is fixed to a load carrying member.
