WebSelf-lubricating bronze or copper alloy sliding plates are also used in expansion bearings in place of elastomeric pads, rollers or rockers. These sliding plates should be at least 12 mm thick and provided with chamfered ends. Sole plates and masonry plates shall have a thickness of at least 20 mm.

Webfixed bearings transfer lateral forces, as described in . LRFD [Section 3], from the superstructure to the substructure units. Both bearing types are set parallel to the direction of structural movement; bearings are not set parallel to flared girders. When deciding which bearings will be fixed and which will be expansion on a bridge, several Webcurved sole plate bearings of the type detailed on standard sheets [BSB SS 1010, 4541C-4541E]. Fixed ... Use bronze plate sliding bearings if load or expansion conditions exceed the permissible values for steel reinforced elastomeric bearing pads [BDM Table 5.7.1.1-2]. WebFriction pendulum bearings (Fig. 4.112B) can be established based on the movement of the weight of the structure (seated on a low-friction slider) over a spherical sliding surface.This kind of bearing combines the sliding mechanism and a restoring force produced by its geometry. In fact, the combination of the lateral displacement and vertical displacement … dvd cover the witness
