【 摘 要 】

In this paper, the partial differential equation of geometric nonlinear dynamic response of laminated rubber bearing is established. Based on the assumption of homogenous column and the nonlinear first-order shear deformation beam theory, the governing equations and boundary conditions of nonlinear dynamic response of laminated rubber bearings are deduced by the stress-strain analysis of micro-unit. The governing equation is a third-coupled geometric nonlinear partial differential equation.
