Description

This paper presents a procedure to model the nonlinear dynamic characteristics of cabinets by using the finite element (FE) method. Duffing's type restoring force is adopted, and its corresponding equation of motion is derived. Assuming the nonlinear stiffness matrix to be diagonal around the first natural frequency, the equation of motion becomes uncoupled. Comparing the numerical results with the experimental ones, the FE model is updated. Finally, the seismic responses of the cabinet are obtained
