Elastomeric bearings are increasingly becoming a design standard in the seismic isolation of large structures and buildings. The rubber bearings used in these designs are made of alternating layers of vulcanized natural or synthetic rubber and thin steel plates. These bearings are expensive to manufacture and are not applicable to smaller structures such as residential buildings. The idea of using inexpensive scrap-rubber tires for making base isolators for residential buildings has been proposed, but the performance of these bearings under seismic forces is not known. Shape factor is an aspect ratio term that is used in describing an elastomeric bearing's dimensional characteristics. Investigation into the performance of bearings with large shape factors has been extensive, but the performance of bearings with small shape factors has not been characterized. Theoretical modeling techniques employed for describing the behavior of rubber bearings with large shape factors are analyzed for the performance of bearings with small shape factors. Deflections of bearings with large shape factors are dominated by shear. As a bearing's shape factor decreases, the governing factor for the deflection changes from shear to bending. As the behavior of the bearing changes from shear to bending, different modeling techniques are necessary to analyze the system. The shape factor at which a bearing goes from shear to bending was established to be in the range of 0.15 to 0.30, which correlates well with theoretical predictions. It was additionally found that the theoretical modeling technique, used to describe the behavior of rubber in compression, is not adequate in predicting the performance of elastomeric bearings with small shape factors.

Concern about reliability of elastomeric bearings is increasing along with the rapid development in application of such devices. Studies on experimental and in-service bearings have revealed the occurrence of permanent and transient changes in engineering properties of these devices. This property loss, however, varies in quality and magnitude, depending on service or environmental conditions at which bearings are employed. Knowledge about the magnitude of the lost property and the rate of degradation is critical for the safe performance of the isolated structure. Availability of such measures helps avoid unnecessary cost and service interruptions of bridge structures by optimizing monitoring and maintenance activities. It is necessary to identify the service and environmental conditions contributing in such degradation phenomenon. A literature review does not indicate the availability of complete and comprehensive studies on this topic. The focus of this research study is to identify and quantify property loss of elastomeric bearings, particularly due to heat, when they are subjected to cyclic lateral load under different environmental conditions. This research also proposes a methodology for a precise and accurate prediction of the temperature profile within the body of an elastomeric bearing. This methodology can be incorporated with the existing numerical models to assess the adequacy of performance of such bearings through seismic events. The reversible changes in characteristics of lead plugs, which take place mainly due to heat, were found to represent the main sources of transient changes in characteristics of an elastomeric bearing. Elastomeric bearings are also subjected to irreversible degradations such as stiffening of bearings as a result of hardening of rubber as when they are exposed to high temperature. High temperature is the result of generation of heat through hysteresis action of lead plugs.

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.

The design and development of elastomeric bridge bearings has been almost entirely empirical, and many conflicts exist regarding current specifications and practices. An effort was made to define and separate those parameters that significantly affect the behavior and performance of elastomeric bridge bearings, toward the end of improving current designs and establishing design criteria. The research included a survey of the literature and available test data, an evaluation (testing) program, and the analysis of data generated.
