Bridge Bearings: Types Details | The Constructor dotorg

Fig.4: Pin Bearing for Bridges Both rocker and pin bearings are mainly employed in steel bridge structure. Rocker and pin bearing should be considered when the bridge movement is adequately known and described, since such bearings can make rooms for both translational and rotational movements in one direction only.
