摘要：

As second shape factor of rubber bearings is small, buckling strain is decrease. In this study, new flare-like structure in order to improve buckling property is proposed. In the conventional structure of rubber bearings, outer diameter of inner rubber is uniform for all layers. In the proposed flare-like structure, outer diameter is not uniform and the diameter of upper and lower layer is larger than that of center layer. First, outline of flare-like structure is introduced. Second, improvement of ultimate properties by flare-like structure is proved theoretically. Third, buckling properties improvement is proved based on finite element analysis. © 2023 Architectural Institute of Japan. All rights reserved.
