Abstract of the Disclosure A supporting bearing for the support of a structure such as a bridge or elevated roadway from a supporting pier or embankment has two systems for accommodating misalignment of the bearing with the expected direction of longitudinal move- ment of the structure and/or non-linear movement such as may be obtained with a curved bridge. These systems may be used alternatively or in addition to one another. In the first system longitudinal guide means which are provided between two relatively longitudinally-movable plate members of the bearing are resiliently mounted to one of the plate members and accommodate the misalignment or non-linear movement by deformation of the resilient mounting, which preferably comprises strips of resilient material interposed between strips of low-friction material and respective edges of the plate members. In the second system the bearing comprises two plate members having between them a layer of resilient material which accommodates vertical, horizontal, rotating and tilting forces between the two members; such as a bearing has a layer of low friction material interposed between the layer of resilient material and the plate member which transmits the load to the resilient layer, so as to facilitate movement between them accommodating the said misalignment and non-linear movements.
