This report presents the results of tests and analyses performed on elastomeric bridge bearings. The focus of this research was the measurement of bearing deformations in the field and assessment of the feasibility of using instrumented elastomeric bearings to monitor bridge condition. The bearing deformations were successful measured in the field during the deck concrete pour and a static truck test. Shear, compression, rotation, and fatigue tests have been carried out in the laboratory and at the manufacturer's facility. Full scale bearings (shape factor 11) were tested at the manufacturer and installed in the field. Model bearings (shape factor 11 and one-quarter the plan area of the full scale bearings) were tested at the manufacturer and in the laboratory. Test bearings (shape factors 5,7, and 10) were tested in the laboratory. The bearing material was 50 Durometer neoprene. The analyses support the testing and considered the bridge-bearing system. The stiffnesses of the bearings are explicitly included in the analyses. A singular characteristic of this experimental research is the focus on the in-service behavior of the bearings.

The purpose of this study was to analyze elastomeric bearing performance on the basis of elastomer hardness, shape factor, reinforcing shim orientation, degree of taper and compressive stress level with the goal of developing a simple design procedure which standardizes as many of those parameters as possible. Particular emphasis was placed on comparing the behavior of flat and tapered bearings. Experimentation included shear, compressive, and rotational stiffness tests, shear and compression fatigue loading, long-term compressive loading, and tests to determine compressive stress limits.
