On the stability of Rubber Isolation Bearings
초록
As an analytical approach, the area reduction formula of rubber bearings has been proposed to account for the reduction in bucking load due to shear. The result obtained from the formula is presumed to be conservative but the degree of conservatism is unknown. This paper describes a numerical study which aims at determining the effect of high shear strain on the critical load of rubber bearings using a finite element analysis program. The results from the finite element analysis which accounts for both the material and geometric non-linearities are compared against the theoretical results in order to examine the validity of the theoretical formulas.
