| 摘要： | The response of elastomeric bridge bearings to imposed rotations was studied using testing and analysis. The program concentrated on steel-reinforced elastomeric bearings. The demand on typical bearings was evaluated by analyzing a range of bridges and evaluating the amplitudes of the axial loads and rotations on the bearings that are likely to occur in practice. During this process, it was found that cyclic axial forces cause larger strains in the elastomer than do the cyclic rotations. However, resource limits in the program precluded cyclic axial testing, and the discovery was anyway made quite late in the program. Thus, in the development of design procedures, the effects of cyclic axial load were taken into account by analysis alone. / NOTE: Transportation research record. / Supplementary Notes: Prepared in cooperation with Washington Univ., Seattle.
