This paper evaluates the effect of geometrical nonlinearity on the buckling load of laminated rubber bearings. In the past research, the author proposed a nonlinear buckling model for shear-bending columns, which revealed the fact that the reduction of lateral stiffness of rubber bearings in a large horizontal displacement depends on their configuration. It has been believed that the low-rise elastomeric columns have a more stable load-displacement characteristics than slender ones. The model, however, clarified the risk of the unstable post-buckling behavior latent in the flat configuration of bearings. On the other hand, the slenderness of elastomeric columns plays an important role to maintain their load supporting capacity in a large deformed area. These analytical discoveries are numerically investigated and compared with some experimental observations.
