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.

Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center. This report summarizes the results of a detailedØevaluation of base isolation elastomeric bearings,Ømanufactured by Skellerup. The report is part of a program to test the performance of 11 seismic isolators and dampers produced by several manufacturers. The devicesØwere tested for stability, response during earthquake simulations, and fatigue and weathering effects.

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.

This thesis primarily predicts the compressive and rotational stiffness of the elastomeric bearing and exams the behavior of elastomeric bearing under compression, rotation, and combination of shear, compression, and rotational loading. The primary purpose of an elastomeric bearing is to distribute the superstructure loads to the substructure. The elastomers used in the elastomeric bearings undergo deformation to allow necessary movement and rotation of the superstructure. Thus, abstract analysis of the behavior of the elastomeric bearing is required. With that end in view, three-dimensional finite element models are developed using the software Abaqus and the results from the finite element analysis are validated with the experimental data from previous literature. The validated finite element models are used for the calculation of compressive and rotational stiffness of the elastomeric bearings and comparisons are made with the analytical closed-form solutions and current code provision (AASHTO, 2017). Moreover, the bearings are subjected to compression, rotation, and a combination of shear, compression, and rotational loading for the prediction of deformed shape, compressive stress, shear stresses, and shear strains.
