Abstract
A bridge bearing assembly comprising an elastomeric bearing pad having side edges and end edges. The bearing pad has contactor surfaces extending upwardly from a mounting plate. A metallic shear controller pin fixed to the mounting plate is positioned adjacent the contactor surfaces. It has surface portions spaced from, but positioned to contact, the contactor surfaces when the bearing pad is deformed in shear in the direction of the end edges. The upper surface of the bearing pad is in contact with a slide plate. Controller pins may be positioned in an opening in, or at end edges of the bearing pad and may be cylindrical or frustoconical. Temperature compensating indicators are provided on the bearing assembly for selectively positioning the slide plate relative to the bearing pad. Preinstallation connectors for securing the slide plate to the bearing pad may be used to help prevent separation of the slide surfaces of the slide plate and bearing pad.
